Which of the following statements about inhibitory synapses is FALSE?
A) The membrane potential of the postsynaptic cell can be hyperpolarized.
B) In presynaptic inhibition, the lower level potential generated interferes with the oncoming action potential.
C) Opening of potassium channels can generate an IPSP.
D) The postsynaptic cell is less likely to generate an action potential.
E) Opening of chloride channels can generate an IPSP.

Question

Quizplus · Accepted Answer

In presynaptic inhibition, the release of neurotransmitter from the presynaptic neuron is reduced, not the interference with the oncoming action potential. This reduction in neurotransmitter release decreases the likelihood of the postsynaptic neuron reaching the threshold to fire an action potential.
