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 .
GABA A receptor-potentiating neurosteroids may preferentially target δ-subunit–containing GABA A receptors, and enhance both tonic and phasic inhibition mediated by GABA A receptors. [54] It is possible that neurosteroids like allopregnanolone may act on other targets , including membrane progesterone receptors, T-type voltage-gated calcium ...
Pregnenolone and its 3β-sulfate, pregnenolone sulfate, like dehydroepiandrosterone (DHEA), DHEA sulfate, and progesterone, belong to the group of neurosteroids that are found in high concentrations in certain areas of the brain, and are synthesized there. Neurosteroids affect synaptic functioning, are neuroprotective, and enhance myelinization.
The y2 subunit is associated with α1-α6 subunits, which are all known α subunits, so these studies do not show which of the α subunits are related to the depressive-like symptoms. Other studies with α2 knockout mice have displayed increased anxiety and depression-like symptoms in conflict-based feeding tests.

Neurochemistry is the study of the different types, structures, and functions of neurons and their chemical components. Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules.
