← Human Body & HealthIf a recovering opioid addict experiences cues related to past drug use, which consequence follows regarding the nucleus accumbens?
A)Reduced dopamine receptor sensitivity occurs
B)GABAergic neuron activity decreases
C)Glutamate reuptake transporters are upregulated
D)Dopamine release transiently increases substantially✓
💡 Explanation
Exposure to drug-related cues triggers increased dopamine release in the nucleus accumbens due to conditioned associations, resulting in craving. This is due to learned associations; therefore, dopamine release spikes, rather than a reduction of receptors or changes in other neurotransmitter systems.
