Current research into neurotransmitter systems has produced the "permissive" hypothesis, which states that
A) low levels of serotonin are sufficient to explain the etiology of mood disorders.
B) the norepinephrine system regulates serotonin levels; if norepinephrine is low, depression will occur.
C) when serotonin levels are low, other neurotransmitter systems become dysregulated and contribute to mood irregularities.
D) the absolute levels of neurotransmitters are more significant in mood regulation than the overall balance of the various neurotransmitters.

Question

Quizplus · Accepted Answer

The "permissive" hypothesis suggests that low serotonin levels disrupt the functioning of other neurotransmitter systems, leading to mood irregularities. It does not propose a direct causal relationship between low serotonin levels and mood disorders. Instead, it emphasizes the importance of the overall balance of neurotransmitters in regulating mood.
