These neurosteroids exert inhibitory actions on neurotransmission.They act as positive allosteric modulators of the GABA A receptor (especially δ subunit-containing isoforms), and possess, in no particular order, antidepressant, anxiolytic, stress-reducing, rewarding, [10] prosocial, [11] antiaggressive, [12] prosexual, [11] sedative, pro-sleep, [13] cognitive and memory-impairing, [citation ...
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 .
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.
Baulieu discovered that DHEA and pregnenolone are produced in the brain and introduced the term "neurosteroids" in 1981. [5] These steroids are active in the nervous system, help repair myelin, protect the nervous system, and enhance memory.

The latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Humans have two olfactory bulbs, one above each nasal cavity. Humans have two ...
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.

One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
