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 .
Neuroscience acknowledges the existence of many types of memory and their physical location within the brain is likely to be dependent on the respective system mediating the encoding of this memory. [9] Such brain parts as the cerebellum, striatum, cerebral cortex, hippocampus, and amygdala are thought
The researchers found that, much like brain cells, these other types of cells responded to the chemical signals by switching on a gene associated with memory storage.
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]
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 brain is also divided into fissures and sulci. [37] The lateral sulcus called the Sylvian Fissure separates the frontal and temporal lobes. The insula is described as being deep to this lateral fissure. The longitudinal fissure separates the lobes of the brain length-wise. Lobes are considered to be distinct in their distribution of vessels ...
