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 that is involved in the nigro-striatal pathway. The mesolimbic pathway (10[1])directs this molecule from the VTA in the midbrain to the nucleus accumbens (“a-cum-bens”) and amygdala. This catecholamine (-5[1])is a precursor to norepinephrine. This neurotransmitter is deficient in those suffering from Parkinson’s disease. (10[1])Addiction to cocaine primarily (10[1])decreases reuptake of this neurotransmitter. (-5[1])For 10 points, name this neurotransmitter involved in the reward pathway that, alongside serotonin, causes the brain to feel pleasure. ■END■ (10[2])
