Increased Activity of the Neurotransmitter Dopamine at Synapses in the Mesolimbic

Multiple Choice

Increased activity of the neurotransmitter dopamine at synapses in the mesolimbic dopamine system is known to cause euphoria.Therefore, a good strategy for the development of new euphoriants is to develop drugs that:

A) Inhibit the sodium cotransporter for dopamine in the nerve terminal.
B) Inhibit the transporter that pumps dopamine into synaptic vesicles.
C) Inhibit tyrosine hydroxylase.
D) Induce enhanced expression of catechol-O-methyltransferase (COMT) .
E) Block voltage-gated calcium channels in the nerve terminals.
