Question

Drugs of addiction activate the ______ system along the _______ reward pathway.

a) Cholinergic; nigrostriatal
b) Adrenergic; Basal forebrain
c) Dopaminergic; Mesolimbocortical
d) Serotonergic; mesencephalic

Answer 1

Drugs of addiction activate the dopaminergic system along the mesolimbocortical reward pathway.

Step-by-step explanation:

The drugs of addiction activate the dopaminergic system along the mesolimbocortical reward pathway.

The mesolimbic pathway consists of dopaminergic projections from the ventral tegmental area (VTA) and substantia nigra (SN) to areas such as the nucleus accumbens and amygdala, which are involved in reward and emotion.

When drugs of addiction activate the mesolimbic pathway, they increase the release of dopamine in these areas, leading to pleasurable feelings and reinforcing the drug-taking behavior.
