Answer:
increased membrane hyperpolarization of "commonsense" neurons.
Step-by-step explanation:
Based on the information provided within the question it can be said that from this any resulting poor decisions associated with ethanol ingestion are likely due to increased membrane hyperpolarization of "commonsense" neurons. In other words it modifies the cell's membrane's ability and makes it more negative, requiring more of a certain stimuli in order to move the membrane to the action potential limit.
