These neurosteroids have excitatory effects on neurotransmission. They act as potent negative allosteric modulators of the GABA A receptor, weak positive allosteric modulators of the NMDA receptor, and/or agonists of the σ 1 receptor, and mostly have antidepressant, anxiogenic, cognitive and memory-enhancing, convulsant, neuroprotective, and neurogenic effects.
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 .
The nervous and endocrine systems often act together in a process called neuroendocrine integration, to regulate the physiological processes of the human body. Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus , controls secretion of pituitary gland hormones, and has subsequently expanded to investigate ...
In pharmacology, GABA A receptor positive allosteric modulators, also known as GABAkines or GABA A receptor potentiators, [1] are positive allosteric modulator (PAM) molecules that increase the activity of the GABA A receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system.
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 end result is that the brain’s pain inhibiting system is activated, thus reducing pain. But, more importantly, “the peptides themselves, when they’re released, give us a sense of well ...
These steroids are active in the nervous system, help repair myelin, protect the nervous system, and enhance memory. Such agents may prove to be useful in the maintenance of brain function during age, and Baulieu suggests that use of DHEA in the elderly may ameliorate certain age-associated deficits including memory loss and depressive mood.
