Eric J. Nestler
Eric J. Nestler is the Nash Family Professor of Neuroscience, Director of the Friedman Brain Institute, and Dean for Academic Affairs at the Icahn School of Medicine at Mount Sinai and Chief Scientific Officer of the Mount Sinai Health System. His research is focused on a molecular approach to drug addiction and depression. He is the co-author of four books and more than 650 peer-reviewed articles, and he serves as principal investigator on 6 NIH grants. Biography Education Nestler is a graduate of Herricks High School in New Hyde Park, New York. He received his B.A., his Ph.D. and his M.D. from Yale University, where he performed his doctoral research in the laboratory of Paul Greengard. He completed his residency in psychiatry at both McLean Hospital in Massachusetts and Yale in 1987. Career Nestler served as Director of the Abraham Ribicoff Research Facilities, as the Founding Director of the Division of Molecular Psychiatry at Yale until 2000, and as Chairman of the Departme ...

Molecular Neurobiology
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject covers topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics and epigenetics on neuronal development, and the molecular basis for neuroplasticity and neurodegenerative diseases. As with molecular biology, molecular neuroscience is a relatively new field that is considerably dynamic. Locating neurotransmitters In molecular biology, communication between neurons typically occurs by chemical transmission across gaps between the cells called synapses. The transmitted chemicals, known as neurotransmitters, regulate a significant fraction of vital body functions. It is possible to anatomically locate neurotransmitters by labeling techniques. It is possible to chemically identify certain neurotransmitters such as catecholamines by fixing neural tissue sect ...

National Institute On Drug Abuse
The National Institute on Drug Abuse (NIDA) is a United States federal government research institute whose mission is to "advance science on the causes and consequences of drug use and addiction and to apply that knowledge to improve individual and public health." The institute has conducted an in-depth study of addiction according to its biological, behavioral and social components. It has also supported many treatments such as nicotine patches and gums, and performed research into AIDS and other drug-related diseases. Its monopoly on the supply of research-grade marijuana has proved controversial. History NIDA's roots can be traced back to 1935, when a research facility (named the Addiction Research Center in 1948) was established in Lexington, Kentucky as part of a USPHS hospital. The Drug Abuse Warning Network (DAWN) and National Household Survey on Drug Abuse (NHSDA) were created in 1972. In 1974 NIDA was established as part of the Alcohol, Drug Abuse, and Mental Health A ...

Epigenetic
In biology, epigenetics is the study of stable phenotypic changes (known as ''marks'') that do not involve alterations in the DNA sequence. The Greek prefix '' epi-'' ( "over, outside of, around") in ''epigenetics'' implies features that are "on top of" or "in addition to" the traditional genetic basis for inheritance. Epigenetics most often involves changes that affect the regulation of gene expression, but the term can also be used to describe any heritable phenotypic change. Such effects on cellular and physiological phenotypic traits may result from external or environmental factors, or be part of normal development. The term also refers to the mechanism of changes: functionally relevant alterations to the genome that do not involve mutation of the nucleotide sequence. Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. Gene expression can ...

CREB
CREB-TF (CREB, cAMP response element-binding protein) is a cellular transcription factor. It binds to certain DNA sequences called cAMP response elements (CRE), thereby increasing or decreasing the transcription of the genes. CREB was first described in 1987 as a cAMP-responsive transcription factor regulating the somatostatin gene. Genes whose transcription is regulated by CREB include: '' c-fos'', BDNF, tyrosine hydroxylase, numerous neuropeptides (such as somatostatin, enkephalin, VGF, corticotropin-releasing hormone), and genes involved in the mammalian circadian clock (PER1, PER2). CREB is closely related in structure and function to CREM (cAMP response element modulator) and ATF-1 (activating transcription factor-1) proteins. CREB proteins are expressed in many animals, including humans. CREB has a well-documented role in neuronal plasticity and long-term memory formation in the brain and has been shown to be integral in the formation of spatial memory. CREB downreg ...
