Etienne-Emile Baulieu, the discoverer of neurosteroids, and a panel of distinguished scientists and clinical researchers exhaustively and cr itically review all facets of neurosteroids involved in behavior, stre ss, memory, depression, anxiety, aging of the brain, and neurodegenera tive diseases. These contributors illuminate the role of neurosteroids in brain development and plasticity and detail their neuromodulatory influence on GABAA, ionotropic glutamate receptors, acetylcholine rece ptors, sigma receptors, and calcium channels. Clearly pointing the way toward novel pharmaceutical agents that may be of significant therape utic value, particularly with regard to aging mental functions, Neuros teroids: A New Regulatory Function in the Nervous System offers neurob iologists, psychiatrists, neurosurgeons, pharmacologists, and geriatri cians the first comprehensive, state-of-the-art review of these import ant bioactive molecules.
