Assume that excessive consumption of ethanol increases the influx of negative chloride ions into "common sense" neurons whose action potentials are needed for you to act appropriately and not harm yourself or others. Thus, any resulting poor decisions associated with ethanol ingestion are likely due to
A) increased membrane depolarization of "common sense" neurons.
B) decreased membrane depolarization of "common sense" neurons.
C) more action potentials in your "common sense" neurons.
D) more EPSPs in your "common sense" neurons.
E) fewer IPSPs in your "common sense" neurons.

Question

Quizplus · Accepted Answer

Excessive consumption of ethanol increases the influx of negative chloride ions into neurons, thus making these neurons less likely to depolarize and fire action potentials. This suggests that the correct answer is B, decreased membrane depolarization of "common sense" neurons, leading to poor decisions associated with ethanol ingestion.
