Neurosteroid Action

Meaning

Neurosteroid Action refers to the rapid, non-genomic modulation of neuronal excitability and synaptic transmission exerted by certain steroid hormones that are either synthesized de novo within the central nervous system or quickly enter the brain from peripheral sources. Key examples include allopregnanolone and dehydroepiandrosterone (DHEA), which act locally to influence neural circuits. This mechanism is distinct from the slower, transcription-based effects of classic steroid hormones, playing a crucial, immediate role in stress response, mood regulation, and cognitive processing.
