|
Monoamine oxidase (MAO) |
Enzyme that breaks down dopamine, norepinephrine, and serotonin |
|
|
Catecho-o-methyltransferase (COMT) |
Enzyme that breaks down dopamine and norepinephrine |
|
|
Mesolimbic dopamine pathway |
Dopamine neurons with somas in the ventral tegmental area and axonsterminating in the limbic system |
|
|
Mesocortical dopamine pathway |
Set of dopamine neurons with somas in the ventral ttegmental area and axons terminating in the cerebral cortex, particularily the prefrontal cortex |
|
|
Nigrostriatal dopamine pathway |
Set of dopamine neurons with somas in the substantia nigra and axons terminating in the basal ganglia |
|
|
Tubero-Infundibular dopamine pathway |
Set of dopamine neurons with somas in the hypothalamus and axons terminating in the pituitary gland, where it plays an important role in the secretion of prolactin. |
|
|
Noradrenergic neurons |
Neurons that synthesize and relase norepinephrine |
|
|
Cholinergic neurons |
Neurons that synthesize and release acetylcholine |
|
|
Acetylocholinesterase |
Enzyme that catabolizes or breaks down, acetylcholine |
|
|
Neurotrophins |
A family of molecules that promote the survival and plasticity of neurons during development and in adulthood |
|
|
Receptor tyrosine kinase |
A family of metabotropic receptors not coupled to a G protein; instead intracellular signaling relies on phosphorylization of a tyrosine kinase molecule located on the intraceullular portion of the receptor |
|
|
Hormones |
Signaling molecules derived from cholestrol and released from glands |
|
|
Oxytocin |
Pituitary hormone important for uterine contraction during childbirth; also contgributes to milk letdown during breast-feeding |
|
|
Vasopressin |
Antidiuretic hormone that cuases the kidneys to absorb water from the bloodstream |
|
|
Melatonin |
Sleep-inducing hormone that plays an important role in circadian rythm, our natural sleep cycle |
|
|
Alzheimer's disease |
A progressive neurological disorder characterized by severe impairments in memory, decision making, attention, motivation, language production and comprehension, and mood regulation |
|
|
Senile plaques |
Degeneerated neurons formed from overproduction of amyloid 42 peptieds, causing cell death |
|
|
Acetylcholinestrerase inhibitors |
Drugs that raise acetylcholine levels by inhibiting acetylcholinesterase |
|
|
Optogenetics |
A research technique that uses light to alter the firing rate of specific types of neurons |
