Neurosteroids are synthesized from cholesterol, which is converted into pregnenolone and then into all other endogenous steroids. Neurosteroids are produced in the brain after local synthesis or by conversion of peripherally-derived adrenal steroids or gonadal steroids. They accumulate especially in myelinating glial cells, from cholesterol or ...
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]

The term "engram" was coined by memory researcher Richard Semon in reference to the physical substrate of memory in the organism. Semon warned, however: "In animals, during the evolutionary process, one organic system—the nervous system—has become specialised for the reception and transmission of stimuli.
Mast cells are white blood cells that interact in the neuroimmune system in the brain. [43] Mast cells in the central nervous system are present in a number of structures including the meninges; [43] they mediate neuroimmune responses in inflammatory conditions and help to maintain the blood–brain barrier, particularly in brain regions where ...
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
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.
