It works: Caitlin is now cooing and smiling. He was paralysed by the virus in 1952 at the age of six. Fantz reported that a two-month-old baby spent twice as long looking at a sketch of the human face as at a bullseye, for instance. When adults view an object disappearing, they tend to show an increase in a particular type of neural oscillation over the right temporal cortex. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. This is the story of the cells that helped to overcome this obstacle, and their controversial origins at a clinic in Sweden. He argues that the newborn has basic attention preferences for things such as faces and speech, and that these preferences shape the brain as it develops. Among the handful of baby labs around the world, this makes the London one stand out. He established a baby lab at University College London (UCL) in 1993, and it moved to more spacious premises at Birkbeck in 1998. The downside of this could be that children who go on to develop autism find it harder to draw general conclusions about what they are seeing, she says. It pretty much blew the family apart, says Gail. It began when a nameless woman who was three months pregnant had a legal abortion in Sweden. by inverting it using prisms. The mean diastolic blood pressure was 5.2 cm Hg (range 4.2 to 6.4). Though today vaccines are extensively filtered, and dont contain any material from the cells theyre grown in, between 1955 and 1963, its been estimated that up to 30 million people were infected in the United States alone. Saul Mcleod, Ph.D., is a qualified psychology teacher with over 18 years experience of working in further and higher education. Gibson, E. J., & Walk, R. D. (1960). But this period is also the most difficult to explore, because many of the standard tools of human neuroscience are useless: babies will not lie awake and still in an imaging machine, and they cannot answer questions or do as they are told. When the apparatus is removed, it again takes time to revert. By 1944 the medical team of the Manhattan Project, headed by Stafford Warren, concluded that a controlled experiment on humans was necessary. At that point, everyone takes a break. Why are the cells so special? since David's real mother had given consent, and programs like this continued on up until the 1960s, when people finally realized that the only practice baby you should really get is your . The main point is that no single measure is able to supply all the evidence required for conclusions about what infants know.. Although this is dependent on visual experience (ie being kept in the light) the time taken to recover from this deprivation is very short compared to the length of deprivation. But that advice, too, is controversial. A London lab is deploying every technology it can use to understand infant brains, and what happens when development goes awry. As investigators design and i One of the things we looked forward to, when we came home from school, was to play with Mark, she says. She sings to baby Caitlin while sticking electrodes on her temples, cheeks and under her chin. This means their use was never restricted, and scientists around the world were able to share them freely with colleagues. On the other side of the bridge was a cliff the chequered pattern was beneath a vertical drop. I hid. They came up with a plan to inject radioactive elements, including polonium, plutonium, and uranium, into civilian patients around the country. Experiment 1. They deny it. After five months, the team saw hints of improvements in the babies' engagement, attention and social behaviour, compared with controls. Later in the day, Caitlin is shown the same video sequence while hooked up to NIRS. Archives of Disease in Childhood - A global paediatric journal - BMJ In the 1960s, Harry Harlow developed an experimental model that took Spitz's studies even further. But fMRI is highly sensitive to movement, so babies can be scanned only if they are sedated or asleep, which has severely limited the technique's use. To assess these deeper areas, researchers need a technique such as functional magnetic resonance imaging (fMRI), which has yielded huge insight into the adult brain. MRC-5 cells, named after the initials of the Medical Research Council where they were collected, were obtained from the lungs of another three-month-old foetus. Four centuries on from the publication of Flamels book, and his fans might be disappointed to hear that no one has made it to 300, let alone discovered the secret to living forever. Chief among them is the requirement for informed consent. But I just dont think it is proper for us to have information about an abnormality without conveying it. But Dr. Lainie Friedman Ross, a pediatrician and medical ethicist at the University of Chicago, said: We dont know if they are medical conditions. Karen found not one, but two autopsy reports, one for his body and another for his brain. As Hayflick has noted previously although perhaps rather insensitively as early as 1984, WI-38 had become the first cultured normal human cell population to ever reach voting age. And if theres any way for me to find that, I would like to put him back together.. Jones is currently piloting 'gaze-contingent' tasks, which enable babies to become active participants in experiments. We will provide updates on efforts to stop the madness of unproven medical tests and interventions, Contact: Vera Hassner Sharav 212-595-8974, 60 Minutes: A Dark Chapter In Medical History They were the raw material of medical research. Feb. 9, 2005. In 2014, Johnson received 2.3 million (US$3.5 million) from a trio of foundations to establish a toddler lab at Birkbeck, in which children aged 18 months to 3 or 4 years old will be attached to wireless forms of electroencephalography (EEG), NIRS and eye-tracking technology as they walk around, play and interact with other children. Karen discovered that patients in the study were put through painful procedures like the pneumoencelphalogram, in which air is injected into the brain before a series of X-rays. Federal inspectors uncovered evidence that thalidomide, which was to be sold under the brand name Kevadon, was passed among doctors and family members with seemingly little awareness that it was . The lab has used such tools to reveal a series of 'firsts' about the infant mind: that babies prefer to look at faces that are looking directly at them, rather than away from them; that they respond to such direct gaze with enhanced neural processing; and that changes in this brain response may be associated with the later emergence of autismthe first evidence that a measure of brain function might be used to predict the condition. What we tend to find is that typically developing babies will always look first, and longer, at the face, before looking at the other objects, she says. The other was made of wire but provided nourishment from an attached baby bottle. Youve gotta have something there. Why are they so special? The cells from WI-38 were never restricted, which means they could be shared freely with scientists around the world (Credit: Andrew Brookes/Getty Images). Then, President Clinton had just ordered thousands of secret documents on government-sponsored human radiation experiments declassified and made available on the Internet. (The chicks were particularly drawn to objects with hen-like necks and faces, but weren't too fussy about the rest of their looks.) Together, the findings suggest that depth perception is an innate process. Imagine puncturing someones spinal cord, drawing fluid out and putting a foreign substance in there. One way to deal with these concerns is to involve the family in decisions about when and how their genetic information is used. The real Flamel was no alchemist he had worked as a scribe, and died in 1418 at the respectable age of 88. If a woman is infected early on, she has a 90% chance of passing the virus to her unborn child, where it can lead to congenital rubella syndrome and a constellation of health problems, from brain damage to hearing loss. 10 Times Well-Loved Scientists Were Total Jerks. section 107 of the US Copyright Law. I was interested in how Ezra would respond, but also in why those tasks were being done, she says. They were the raw material of medical research, says Susan Lederer, who teaches medical history at Yale University. I came from Europe after the war, where all these horrendous things happened, says Rosemarie. As it was possible to eliminate or control the influences of other senses (such as touch from the rats whiskers) they ensured it was a valid test of visual perception. The future health of infants and children is dependent on the performance of clinical research in which infants participate. Their mother also participated in the experiment. The researchers used 113 newborns ranging in age from one hour to three days old as test subjects. Experiments based on gaze measurements have been the field's workhorse ever since. The independent variable (IV) was whether the infant was called by its mother from the cliff side or the shallow side (of the visual cliff apparatus). In 2005, Johnson and his colleagues combined observations of looking time with electrical measurements of brain activity to investigate Piaget's claim that infants younger than nine months do not understand the permanence of an object that has vanished. They had him cremated and placed his ashes in a private mausoleum. Gaze experiments have led some researchers to conclude that, far from being blank slates, babies are born with an innate appreciation of number and human faces, as well as the ability to recognize when their mother's native language is being spokena familiarity proposed to develop through hearing speech while in the womb. A report in The New York Times (Feb 21) reveals that "An influential federal advisory group plans to recommend in the next few weeks that all newborns be screened for 29 rare medical conditions." This gave them the opportunity to observe the animals response and to see whether it learned from the experience of not falling downwards.. I ran. Lederer says using captive populations meant big money for medical researchers: It would even be an advantage in applying for grant money, because you dont have to go to the problem of recruiting subjects. In the case of Sonoma State, records show that when the study began, cerebral palsy admissions there jumped by 300 percent. Years later it came out that many babies were treated with radiation. Without it, you and I might not even be alive, says Stuart Jay Olshansky, an expert in biodemography and gerontology at the University of Illinois, Chicago. The visual cliff. On Feb. 9, CBS 60 Minutes reported about the buried secrets at Sonoma State Hospital (now Sonoma Developmental Center), where 3,500 children with disabilities lived in the 1950s and 1960s. Do I feel it will be difficult for physicians and caretakers to deal with this? Dr. Howell said. But the team acknowledged that many of the results had wide confidence intervals and that it is too early to say whether the intervention will have long-term effects. Another reason WI-38 has become so ubiquitous is that a quirk of the American legal system at the time of its discovery: it wasnt possible to patent living things. The connection between the chilling origins of many cell lines and the benefits they provide is perhaps most striking in the development of the rubella vaccine. She acknowledges that the experiments were not intended, nor were they, of any benefit to the children who served as mere guinea pigs. Knowledge awaits. A recently released book details the experiments the US government undertook, over decades, on their own unknowing citizens to test the effects of radiation. Research shows why 1960s RSV shot sickened children. Simply looking at the drop, or being encouraged to cross it by their mothers, may have distressed the babies they didnt know the glass was there to save them. Out of curiosity, I started to read it, and they mentioned patients that were in state-run hospitals being used, says Karen. sent to the Karolinska Institute in northwest Stockholm, for the very reason that their mother was infected with the virus, 90% chance of passing the virus to her unborn child. They didnt even say where they were calling from. There have been literally thousands of experiments done with these looking-time methods, Aslin says, and by and large it is a pretty reliable technique; you can have two labs running the same experiment and you get the same results. But Aslin and Kagan are two of a growing number of researchers who think that such infant studies should be viewed with caution: it can be dangerous to infer too much about the workings of a baby's mind from just their fleeting glanceand they worry that some labs do not control for confounding factors as well as they should. Experiments on Newborns. Even today, the medical research establishment and those who set government health care policy appear to have learned little from the lessons of the radiation experiments. Johnson hopes that investigations in the toddler lab, when they start, might also eventually find a practical use, helping researchers to devise ways to boost cognitive, attention and memory skills. The researchers pause for a moment, while Caitlin's mother takes a photo of her science baby on her phone. The dependent variable (DV) was whether or not the child would crawl to its mother. . Harlow removed young monkeys from their natural mothers a few hours after birth and left them to be . But you know, theres just nothing in our archives about the research you are talking about. If these studies were being done, if there are patients from here being sent for radiation studies, is that a stain on the hospital record, asks Mabrey. Achieving a proper balance between this social good and the obligation to protect infants who participate in research is a significant challenge. It profoundly affected me., Rosemarie had committed 3-year-old Mark to Sonoma State Hospital, the largest institution for children in California. School for Scandal: In addition to conducting hepatitis experiments, Willowbrook's staff physically abused residents. Children were the raw material of medical research - CBS 60 Minutes /Newborn Screening for 29 conditions - NYT . Lederer told 60 Minutes that she wasnt shocked by the findings because "researchers have been using disabled children in experiments for over a century." The researchers used 113 newborns ranging in age from one hour to three days old as test subjects. I believe that Dad did what he felt was best for the family. I just needed to know and, no matter what it was, I needed to know. The laboratories, however, are largely empty and painted a dull battleship greya deliberate choice, because babies are easily distracted. Polio once left people with lifelong conditions, but has been effectively killed off in the wild thanks to a vaccine (Credit: Getty Images). The baby seems unsure, so a research assistant appears, brandishing a garish musical telephone. One man, 74-year-old Paul Alexander, is still trapped in an iron lung. By the time the answer is in, it may be too late for treatment to do much good. The dispute centers on how useful the test findings would be. There is a well-worn adage in show business that you should never work with children or animals. That was the opinion that Johnson quickly reached when he began infant research: the reliance on looking time and observations alone were unsatisfying. Using the same apparatus, Gibson and Walk tested chicks, lambs and kids (young goats) all less than 24 hours old. It turns out ordinary human cells can only divide between 40 and 60 times before they undergo a violent, pre-determined death. Please join meon Wednesday, April, The last generation of Holocaust survivors and their children express their concerns about current events A Five-Part, Copyright 2023 Alliance for Human Research Protection, Children were the raw material of medical research /Newborn Screening for 29 conditions, Panel to Advise Testing Babies for 29 Diseases, Join Robert F Kennedy Jr. April 19 in Boston, Vera Sharavs documentary Never Again is Now Global now available. She was very hard on them, the girls., Doctors advised the Dal Molins to commit their son, so Bill told Rosemarie they had to send Mark to an institution. He ran extremely high fevers that none of us here right now would live through, says Karen. But life would be a struggle for the Dal Molins because Mark was born with cerebral palsy, a condition that cripples the body, but not necessarily the mind. Sample: 36 infants ranging in age from six months to 14 months. The investigation of the nature-nurture issue in perception didnt end with Gibson and Walks research. And it wouldnt surprise me that there were things we would find consider questionable today., It took two years and a court order for Karen to get Sonoma State to turn over Marks medical records. Handicapped children. Unless their families claimed them, the children ended up in a community grave with the ashes of 500 other people, or buried in a empty field without a headstone to mark their passing. In the late 1960s and 1970s, the American Pediatric Society-Society for Pediatric Research meeting was a very exciting place to be, with many new discoveries presented. Before Hayflicks discovery, scientists had got around the division limit by continually replenishing their cell supplies with fresh ones from new animals, or using cancerous cells since cancer doesnt play by the same rules as healthy tissue, and will keep growing indefinitely. The studies using other species are quasi (laboratory) experiments. The folks that remain here are undisturbed and available for family visitation, says Murphy. Findings such as these tell us that, at least in some respects, depth perception is learned. ", Another ill-advised, government sponsored screening initiative was recommended by the Presidents New Freedom Commission on Mental Health the entire population is to be screened for undetected mental health disorders even though no valid, objectively verifiable screening tools exist. My work, I think, goes for a middle ground, he says. They then began working with Birkbeck researchers to adapt it to answer more fundamental questions. Behind a curtain, postdoc Jannath Begum Ali checks the data streaming in on her monitor. The federal advisory group recommended informing the parents of such results. In total, the cells are likely to have spared 10.3 million lives. 60 Minutes Wednesday learned that between 1955 and 1960, the brain of every cerebral palsy child who died at Sonoma State was removed and studied. Car Sales to Be Electric by 2032. Lederer read the study that was conducted at Sonoma State Hospital, and says the children underwent painful experimentation for which they received no direct benefit. It seems clear that these were intended to enlarge knowledge about cerebral palsy, adds Lederer. One of the first to do so was Jean Piaget, a Swiss psychologist who used detailed observations of infants and older children to gain insight into how they understand the worldincluding, famously, by hiding an object to see whether infants try to find it. In 1612, the streets of Paris were alive with a tantalising rumour that a man had achieved immortality. She is participating in a study to assess the development of mimicry in babies: the unconscious tendency of people to frown when someone else frowns, or smile when they smile. With just half of a planned 15-minute observation complete, Ezra has defecated. Scientific American, 206 (5), 62-73. And how can we justify continuing to use them? Both sides agree that the tests "unintentionally pick up about 25 other conditions, in addition to the 29 that the screening is intended to find. Researchers have measured infants' interest and attention mostly by tracking their gazebut even this method has been criticized as crude. In the 1960s, researchers at the University of California began an experiment to study changes in blood pressure and blood flow. The visual cliff apparatus allowed them to conduct an experiment in which the optical and tactile . What colours are present? There has been some controversy over the use of cells produced in this manner (Credit: Claudio Divizia /EyeEm/Getty Images). Some of the conditions are well known, like sickle cell anemia, some obscure, affecting less than 100 infants a year. Other, less dramatic, changes to perception can be induced by shifting the field of view slightly to one side then testing depth perception, eg by the ability to point accurately to a target. I worked in Harlow's lab as as an undergraduate student in 1951/52. Would going ahead with the full list of tests result in more good than harm, physically and emotionally? An infant may look longer in order to relate the event to what it already knows, says Kagan. By late afternoon, his mother is tucking him into the pushchair for his journey homea 1-hour 45-minute journey to Bristol by train. While the severely disabled languished in overcrowded rooms, the able-bodied were put to work in the institutions dairies and orchards. Julia Russell has over 25 years of experience as a Psychology teacher. The brain undergoes more change during the first two years of life than at any other time: consciousness, traits of personality, temperament and ability all become apparent, as do the first signs that development could be drifting off course. As if frightening the life out of orphans wasn't bad enough, researchers at the . I just remember one day coming home from school and the house was very quiet, says Karen, who never got to say goodbye to her brother. This article is reproduced with permission and wasfirst publishedon November 4, 2015. After a two year battle to obtain her brothers medical records, a court order finally forced Sonoma to release them. The American literary scholar Roger Shattuck called this kind of research study "The Forbidden Experiment" due to . A family can have their first child in one state where 25 conditions are screened and then move to another where only four are screened.. In the 1960s, the polio vaccine used in the United States had been hit by calamity. It is no exaggeration to say that without looking-time measures, we would know very little about nearly any aspect of infant development, says Aslin. Experiments on Newborns; In the 1960s, researchers at the University of California used newborns as the subjects of their tests to find out more about blood pressure. The second experiment aimed to explore this possibility using animals. The visual cliff is an apparatus created by psychologists Eleanor J. Gibson and Richard D. Walk at Cornell University to investigate depth perception in human and other animal species. This time the abortion happened in England in 1966 for psychiatric reasons. The incident is unlikely to happen again today, because human tissue is regulated in the United States. Read about our approach to external linking. Baby Caitlin stares intently at the screen; she does not seem to be copying the woman's actions. Secondly, its difficult to find cells that scientists can grow in the laboratory an essential step in the production of many drugs and vaccines. Nobody told me. Thanks for reading Scientific American. ', Things got stranger still when Karen noticed an article in the local paper saying 16,000 people, including children, had been used in radiation experiments. The visual cliff. MMV, CBS Worldwide Inc. All Rights Reserved. Soon after Hayflick discovered that cells are mortal, he realised that if you siphon some off each time they divide and freeze them, a single source can theoretically provide an almost unlimited supply around 10,000,000,000,000,000,000,000 (10 sextillion) in total. But after 40 years, they still struggle with the decision to institutionalize their brother. Reporting test data for which there are no systems in place for follow-up testing and treatment is not rejecting paternalism, but it is patient abandonment. In any event, Dr. Howell said, noting that states were plunging into testing programs: Its not really a question of, Should we expand newborn screening? Its happening. What I learned from this experience is the value of facts and verified statements about animal behavior. So I went to the recorders office, says Karen. In a series of controversial experiments conducted during the 1960s, Harlow demonstrated the powerful effects of love and in particular, the absence of love. Psychological Review, 4 (4), 341. 6. We dont know what a true positive test means. Mimicry serves important social functions in adults and has even been suggested to be the 'social glue' that binds us together, says Carina de Klerk, who is leading that study at Birkbeck. No. The procedure was a rigorously controlled laboratory test so offered a reliable but also safe measure of depth perception. Swollen eyes, seizures, those things can fit in with radiation poisoning. Marks records contained another shock. Below the screen, a box is shining infrared light at his cornea, and then capturing and processing the reflected light to work out the direction of his gaze. Vision without inversion of the retinal image. The tests conducted included: inserting a catheter through the umbilical cord and into the newborn . Discover world-changing science. Hold on to your butts, because all of the following experiments really happened. I never dreamed that in this country, they would do experimenting children. (1962). The waiting room is brightly decorated and scattered with easy-to-clean toys. These additional conditions show up as abnormalities, but no one knows what they mean. My wife and I, we have a very close friend of ours who is suffering from the consequences of a polio exposure as a child today.. When you looked into his eyes, he communicated through his eyes. Hed laugh and giggle and kick, and just screech when he saw us. But by 3, Mark could neither walk nor talk, which meant his mother, Rosemarie, had to care for him. Kohler, I. Most WI-38 cells have 50 divisions left, which each take 24 hours to complete, so they can be grown continuously for 50 days before you need to start again. In these situations the world at first seems upside down, or muddled, but over time the brain adapts to the change and normal perception returns. For his PhD project in the 1980s, he investigated whether day-old chicks formed social attachments to any object placed in their pen, or if they preferred ones that resembled a mother hen. I knew he was dead. From that day on, Karen and her sisters, Chris and Gail, say they never spoke Marks name again. In fact, if you multiply the number of cells in the human body by the average time it takes for cells to reach the Hayflick limit, you end up with 120 years. Dr. Norman Fost, a professor of pediatrics and director of the program in medical ethics at the University of Wisconsin, points out: The majority of newborn screening tests have failed. The quest for immortality took another blow in 1961, this time in a modern laboratory in Philadelphia. In the 1960s, the polio vaccine used in the United States had been hit by calamity. When asked if patients at state hospitals were used in medical research, Murphy says, Ive read that there has been things like using rattlesnake venom of epilepsy. Dear Supporter of Freedom, Autonomy and the Right to Voluntary Informed Consent! The study of which Ezra is part aims to extend this work by collecting more-detailed measures from over 400 familiesand to identify those features that are strongly associated with the later onset of a developmental disorder. Scientists there have pioneered techniques such as infant near-infrared spectrometry (NIRS), which measures brain activity by recording the colour, and therefore the oxygenation, of blood. Meanwhile, the techniques continue to evolve. Any material collected is subject to the Common Rule a set of ethical standards introduced in 1981, which researchers must comply with in order to receive federal funding. In my heart, I know that is true. and my mom was told I was too big and had an enlarged thymus and radiation was necessary to prevent me from growing to gigantic proportions. Sign up and be the first to find out the latest news and articles about what's going on in the medical field. Scientists have been attempting practical research with babies since the middle of the twentieth century. And why can't people remember their earliest months and years? Oblivious to his important role in science, Ezra furrows his brow into a frown. Babies in 28 families with an older sibling with autism were randomly assigned to a group in which they were visited by a therapist at least six times between the ages of seven and ten months, and were compared with a group of high-risk babies who received no therapy.
