This substance can be broken down by COMT in the prefrontal cortex, which it connects to the ventral tegmental area via the mesocortical pathwayl.
This substance can be broken down by COMT in the prefrontal cortex, which it connects to the ventral tegmental area via the mesocortical pathwayl. It can also operate via the tuberoinfundibular pathway, and it inhibits the secretion of prolactin. This precursor of norepinephrine is primarily produced in the (*) substantia nigra. Deficiency of this catecholamine can cause a degenerative disease whose most visible symptom is persistent tremors, since this neurotransmitter helps carry out voluntary movement. It is also associated with reward-seeking and pleasure behaviors. For 10 points, name this neurotransmitter whose deficiency leads to Parkinson's disease and whose precursor is L-dopa.
