All of the following occur for GABA neurons from chronic alcohol administration except:
A) the density of GABAA receptors is reduced.
B) GABAA receptors become less affected by alcohol.
C) dopamine becomes more effective for inhibiting GABA neurons.
D) minimal changes in endorphin levels, disinhibiting GABA neuron activity.

Question

Quizplus · Accepted Answer

Chronic alcohol administration decreases the effectiveness of dopamine in inhibiting GABA neurons, leading to increased excitability of these neurons. This contributes to the development of alcohol dependence and withdrawal symptoms. The other options are correct: the density of GABAA receptors is reduced, making synapses less responsive to GABA; the receptors become less sensitive to alcohol, requiring higher doses for the same effect; and endorphin levels are increased, enhancing GABA neuron activity.
