Which event is LEAST likely to directly influence postsynaptic membrane potential following neurotransmitter release?
Show answer and explanation
Correct answer: Rate of vesicle synthesis in the presynaptic neuron
While vesicle synthesis is important for long-term neurotransmitter availability, it does not directly influence the immediate postsynaptic membrane potential after release; that is determined by receptor binding, channel opening, and neurotransmitter clearance.
