Genes, Brains, and Behavior: Imaging Genetics for Neuropsychiatric Disorders

Genes, Brains, and Behavior

Behavior is defined as the directed action of an animal in response to a stimulus. In multicellular animals, behavior is the product of the nervous system. Behavioral phenotypes are often conserved across distant taxa and are heritable. Yet, the role of genetics and evolution in determining behavior has been controversial for much of the first half of the twentieth century, often paraphrased as...

Genes, behavior, and behavior genetics.

According to the 'first law' of behavior genetics, 'All human behavioral traits are heritable.' Accepting the validity of this first law and employing statistical methods, researchers within psychology, sociology, political science, economics, and business claim to have demonstrated that all the behaviors studied by their disciplines are heritable-no matter how culturally specific these behavio...

Proteomic investigation of epigenetics in neuropsychiatric disorders: a missing link between genetics and behavior?

Neuropsychiatric disorders affect a large segment of the human population and result in large costs to society. The majority of such disorders have unknown underlying causes. Recent evidence suggests an important role for epigenetic regulation in the emergence of neuropsychiatric disease. Epigenetics may provide a link between genetic and environmental factors and behavior. Epigenetic signaling...

Imaging Genetics and Psychiatric Disorders

Imaging genetics is an integrated research method that uses neuroimaging and genetics to assess the impact of genetic variation on brain function and structure. Imaging genetics is both a tool for the discovery of risk genes for psychiatric disorders and a strategy for characterizing the neural systems affected by risk gene variants to elucidate quantitative and mechanistic aspects of brain fun...
