Neurosteroids, also known as neuroactive steroids, are endogenous or exogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors. [1] [2] The term neurosteroid was coined by the French physiologist Étienne-Émile Baulieu and refers to steroids synthesized in ...
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 .
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 form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.
Many functions of the brain are somewhat localized to associated areas like motor and speech ability. Functional associations of brain anatomy are now being complemented with clinical, behavioral, and genetic correlates of receptor action, completing the knowledge of neural signalling (see also: Human Cognome Project). The signal paths of ...
In general, behavioral neuroscientists study various neuronal and biological processes underlying behavior, [42] though limited by the need to use nonhuman animals. As a result, the bulk of literature in behavioral neuroscience deals with experiences and mental processes that are shared across different animal models such as: Sensation and ...
Pherines specifically target nasal chemosensory cells [5] [6] and mediate selective modulation of brain areas like the limbic amygdala, hypothalamus, hippocampus, and prefrontal cortex. [7] In clinical trials, pherines formulated for intranasal administration in ultra low doses (nanogram to low microgram quantities) showed rapid onset of ...
The hypothalamus is a distinct part of the brain that is made up of neurons and its main purpose is to maintain homeostasis. [5] The hypothalamus also plays an important part in survival of the individual by integrating the interactions between hormonal and behavioral processes, such as, eating behavior and aggressive behavior.
