Receptors for this molecule contain two binding pockets that both interact with the agonist Rotigotine. Apo-morphine is a non-selective agonist of this molecule (10[1])that is involved in the nigro-striatal pathway. (10[1])The mesolimbic pathway (10[2])directs this (10[1])molecule from the VTA in the midbrain to the nucleus accumbens (10[2])(“a-cum-bens”) and (10[1])amygdala. (10[4])This (10[1])catecholamine (-5[1])is a precursor to norepinephrine. (-5[4])This (-5[1])neurotransmitter (10[2])is deficient (-5[1])in those (10[2]-5[1])suffering (-5[1])from (-5[1])Parkinson’s (10[2]-5[1])disease. (10[8]-5[2])Addiction (10[1])to cocaine (10[1])primarily (10[2]-5[1])decreases (10[2])reuptake of this neurotransmitter. (10[3]-5[3])For 10 points, (-5[1])name (-5[1])this neurotransmitter involved in the reward pathway (10[1])that, (10[1])alongside (10[1])serotonin, (10[1])causes the brain to feel pleasure.
