The 5-HT 2A receptor is a subtype of the 5-HT 2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). [4] The 5-HT 2A receptor is a cell surface receptor, [5] but has several intracellular locations. [6] Like all 5-HT 2 receptors, the 5-HT 2A receptor is G q /G 11-protein coupled.
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
The 5-HT 2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). [1] The 5-HT 2 subfamily consists of three G protein-coupled receptors (GPCRs) which are coupled to G q /G 11 and mediate excitatory neurotransmission , [ 2 ] including 5-HT 2A , 5-HT 2B , and 5-HT 2C .
A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina. In other cases it represents other stimulus properties ...

Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
[38] [39] Lisuride acts preferentially or exclusively on the non-heteromerized 5HT2A receptors, which are not capable of inducing psychedelic effects. Due to this, lisuride is capable of reducing the hallucinogenic effects of these drugs through competitive antagonistic activity (producing the effect of a silent antagonist in the presence of ...
Cortical maps are collections (areas) of minicolumns in the brain cortex that have been identified as performing a specific information processing function (texture maps, color maps, contour maps, etc.).
