Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles into the circulation in response to extracellular fluid hypertonicity (hyperosmolality). AVP has two primary functions. First, it increases the amount of solute-free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons. Second, AVP constricts arterioles, which increases peripheral vascular resistance and raises arterial blood pressure.
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, reproduction, childbirth, and the period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to sexual activity and during labour. It is also available in pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth. In its natural form, it also plays a role in bonding with the baby and milk production. Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of childbirth, this stimulates production and release of more oxytocin and an increase in the intensity and frequency of contractions. This process compounds in intensity and frequency and continues until the triggering activity ceases. A similar process takes place during lactation and during sexual activity.
The National Institute of Neurological Disorders and Stroke (NINDS) is a part of the U.S. National Institutes of Health (NIH). It conducts and funds research on brain and nervous system disorders and has a budget of just over US$2.03 billion. The mission of NINDS is "to reduce the burden of neurological disease—a burden borne by every age group, every segment of society, and people all over the world". NINDS has established two major branches for research: an extramural branch that funds studies outside the NIH, and an intramural branch that funds research inside the NIH. Most of NINDS' budget goes to fund extramural research. NINDS' basic science research focuses on studies of the fundamental biology of the brain and nervous system, genetics, neurodegeneration, learning and memory, motor control, brain repair, and synapses. NINDS also funds clinical research related to diseases and disorders of the brain and nervous system, e.g. AIDS, Alzheimer's disease, epilepsy, muscular dystrophy, multiple sclerosis, Parkinson's disease, spinal cord injury, stroke, and traumatic brain injury.
The National Institute of Mental Health (NIMH) is one of 27 institutes and centers that make up the National Institutes of Health (NIH). The NIH, in turn, is an agency of the United States Department of Health and Human Services and is the primary agency of the United States government responsible for biomedical and health-related research.
Paul Donald MacLean was an American physician and neuroscientist who made significant contributions in the fields of physiology, psychiatry, and brain research through his work at Yale Medical School and the National Institute of Mental Health. MacLean's evolutionary triune brain theory proposed that the human brain was in reality three brains in one: the reptilian complex, the limbic system, and the neocortex.

Institute, an affiliate of UC Davis, engaged in interdisciplinary research into the causes and treatment of autism and related neurodevelopmental disorders. Amaral joined the UC Davis faculty as a Professor in the Department of Psychiatry and the Center for Neuroscience and as an investigator at the California Regional Primate Research Center in 1991. Since 1995, he has been a professor of psychiatry in the UC Davis School of Medicine, with an appointment to the Center for Neuroscience.
High-functioning autism (HFA) is an autism classification where a person exhibits no intellectual disability, but may exhibit deficits in communication, emotion recognition and expression, and social interaction. HFA is not included in either the American Psychological Association's DSM-5 or the World Health Organization's ICD-10, neither of which subdivides autism based on intellectual capabilities.
Vasopressin receptor 1A (V1AR), or arginine vasopressin receptor 1A is one of the three major receptor types for vasopressin, and is present throughout the brain, as well as in the periphery in the liver, kidney, and vasculature.
Steven Edward Hyman is Director of the Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard in Cambridge, Massachusetts. He is also Harvard University Distinguished Service Professor of Stem Cell and Regenerative Biology. Hyman was Provost of Harvard University from 2001 to 2011 and before that Director of the U.S. National Institute of Mental Health (NIMH) from 1996 to 2001. Hyman received the 2016 Rhoda and Bernard Sarnat International Prize in Mental Health from the National Academy of Medicine for "leadership in furthering understanding and treatment of psychiatric disorders as biological diseases".
C. Sue Carter is an American biologist and behavioral neurobiologist. She is an internationally recognized expert in behavioral neuroendocrinology. In 2014 she was appointed Director of The Kinsey Institute and Rudy Professor of Biology at Indiana University. Carter was the first person to identify the physiological mechanisms responsible for social monogamy.
Susan Swedo is a researcher in the field of pediatrics and neuropsychiatry. Beginning in 1998, she was Chief of the Pediatrics & Developmental Neuroscience Branch at the US National Institute of Mental Health. In 1994, Swedo was lead author on a paper describing pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a controversial hypothesis proposing a link between Group A streptococcal infection in children and some rapid-onset cases of obsessive-compulsive disorder (OCD) or tic disorders such as Tourette syndrome. Swedo retired from the NIH in 2019, and serves on the PANDAS Physician Network.

Gerald D. Fischbach is an American neuroscientist. He received his M.D. from the Weill Cornell Medical College of Cornell University in 1965 before beginning his research career at the National Institutes of Health in 1966, where his research focused on the mechanisms of neuromuscular junctions. After his tenure at the National Institutes of Health, Fischbach was a professor at Harvard University Medical School from 1972–1981 and 1990–1998 and the Washington University School of Medicine from 1981–1990. In 1998, he was named the director of the National Institute of Neurological Disorders and Stroke before becoming the Vice President and Dean of the Health and Biomedical Sciences, the Dean of the Faculty of Medicine, and the Dean of the Faculty of Health Sciences at Columbia University from 2001–2006. Gerald Fischbach currently serves as the scientific director overseeing the Simons Foundation Autism Research Initiative. Throughout Fischbach's career, much of his research has focused on the formation and function of the neuromuscular junction, which stemmed from his innovative use of cell culture to study synaptic mechanisms.
The Research Domain Criteria (RDoC) project is an initiative of personalized medicine in psychiatry developed by US National Institute of Mental Health (NIMH). In contrast to the Diagnostic and Statistical Manual of Mental Disorders (DSM) maintained by the American Psychiatric Association (APA), RDoC aims to address the heterogeneity in the current nosology by providing a biologically-based, rather than symptom-based, framework for understanding mental disorders. "RDoC is an attempt to create a new kind of taxonomy for mental disorders by bringing the power of modern research approaches in genetics, neuroscience, and behavioral science to the problem of mental illness."
