Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control. [1] Each pathway is a set of projection neurons, consisting of individual dopaminergic neurons.
Dopamine receptor D 2, also known as D 2 R, is a protein that, in humans, is encoded by the DRD2 gene.After work from Paul Greengard's lab had suggested that dopamine receptors were the site of action of antipsychotic drugs, several groups, including those of Solomon H. Snyder and Philip Seeman used a radiolabeled antipsychotic drug to identify what is now known as the dopamine D 2 receptor. [5]
The D 2-like receptors [1] are a subfamily of dopamine receptors that bind the endogenous neurotransmitter dopamine. The D 2-like subfamily consists of three G-protein coupled receptors that are coupled to G i /G o and mediate inhibitory neurotransmission, of which include D 2, D 3, and D 4. For more information, please see the respective main ...
The role between dopamine and pathological gambling may be a link between cerebrospinal fluid measures of dopamine and dopamine metabolites in pathological gambling. [52] Molecular genetic study shows that pathological gambling is associated with the TaqA1 allele of the Dopamine Receptor D2 (DRD2) dopamine receptor.
The dopamine pathway starts at the ventral tegmental area (VTA) and is routed to the nucleus accumbens and the prefrontal cortex for ultimate dopamine release that yields reward and reinforcement. This helps in feeling pleasure or enjoyment of a certain stimuli and reinforcing that positive feeling when that initial stimuli occurs again.
A dopamine agonist is a compound that activates dopamine receptors. There are two families of dopamine receptors, D 1-like and D 2-like. They are all G protein-coupled receptors. D 1 - and D 5-receptors belong to the D 1-like family and the D 2-like family includes D 2, D 3 and D 4 receptors. [1]
Dopamine released at this site inhibits the secretion of prolactin from anterior pituitary gland lactotrophs by binding to dopamine receptor D2. Some antipsychotic drugs block dopamine in the tuberoinfundibular pathway, which can cause an increase in the amount of prolactin in the blood (hyperprolactinemia).
The substantia nigra is located in the ventral midbrain of each hemisphere. It has two distinct parts, the pars compacta (SNc) and the pars reticulata (SNr). The pars compacta contains dopaminergic neurons from the A9 cell group that forms the nigrostriatal pathway that, by supplying dopamine to the striatum, relays information to the basal ganglia.
