Molecular Neurobiology for Practicing Physicians, Part 1:
Overview of Gene Activation by Neurotransmitters

Stephen M. Stahl, M.D., Ph.D.


Issue: Molecular biology is increasingly relevant to practicing physicians because it helps to explain the biological basis of mental disorders and especially the molecular and pharmacologic mechanism of action of psychotropic drugs. The ultimate action of neurotransmitters and drugs that act at receptors is to alter the activity of neuronal genes.


 

This feature begins the first of a series of articles on molecular neurobiology for the practicing psychiatrist. Shown here is the "visual vocabulary" for each of the critical elements in the activation of neuronal genes by neurotransmitters.1 Subsequent lessons will demonstrate how each element of this visual vocabulary relates to the others, resulting ultimately in the expression of genes that regulate neuronal functioning in the target neuron.
