The physiological importance of neurosteroids is beginning to be understood. These steroids potentially have roles in sedative/hypnotic behavior, anxiety, learning, and memory. At the cellular level, neurosteroids affect neuronal excitability, synaptic plasticity and cell proliferation and survival. Early findings hold promise for future strategies to treat specific psychologicalconditions and neurological diseases. This Brief will focus on the current state of understanding of brainderived neurosteroids.SpringerBriefs in Neuroscience,2191-558XNeuroendocrinologySteroid hormonesNeurohormonesNeuroendocrinology.Steroid hormones.Neurohormones.612.8/042King Steven R94041MiAaPQMiAaPQMiAaPQBOOK9910437845103321Neurosteroids and the Nervous System2502971UNINA
