Neurosteroids, also known as neuroactive steroids, are endogenous or exogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors. [1] [2] The term neurosteroid was coined by the French physiologist Étienne-Émile Baulieu and refers to steroids synthesized in ...
This is a list of neurosteroids, or natural and synthetic steroids that are active on the mammalian nervous system through receptors other than steroid hormone receptors. It includes inhibitory , excitatory , and neurotrophic neurosteroids as well as pheromones and vomeropherines .
A neurosteroidogenesis inhibitor is a drug that inhibits the production of endogenous neurosteroids.Neurosteroids include the excitatory neurosteroids pregnenolone sulfate, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEA-S), and the inhibitory neurosteroids allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol, among others.

Little is known about where different complexes are located in the brain, complicating drug discovery. [7] For example, the binding site of neurosteroids in the GABA A receptor is not known [9] and barbiturates bind at a beta subunit that is distinct from the benzodiazepine binding site.
Pherines specifically target nasal chemosensory cells [5] [6] and mediate selective modulation of brain areas like the limbic amygdala, hypothalamus, hippocampus, and prefrontal cortex. [7] In clinical trials, pherines formulated for intranasal administration in ultra low doses (nanogram to low microgram quantities) showed rapid onset of ...
The first half of the 20th century saw psychology and psychiatry as largely phenomenological, in that behaviors or themes which were observed in patients could often be correlated to a limited variety of factors such as childhood experience, inherited tendencies, or injury to specific brain areas. Models of mental function and dysfunction were ...
