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 hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]

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.

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.
The transition of a memory from short term to long term is called memory consolidation. Little is known about the physiological processes involved. Two propositions of how the brain achieves this task are backpropagation or backprop and positive feedback from the endocrine system.
People with this condition may suffer from excessive fatigue, exercise intolerance, brain fog, insomnia and dizziness, according to the Yale researchers. These typically develop within a day or ...
