Which of the following occurs with presynaptic inhibition in a specific neuron
A)An IPSP occurs on the postsynaptic cells.
B)All excitatory information being fed into the cell is depressed.
C)The release of excitatory transmitter from a specific presynaptic excitatory input is depressed.
D)An EPSP occurs in the postsynaptic cells.

Question

Quizplus · Accepted Answer

Presynaptic inhibition involves the reduction of the release of neurotransmitter from a specific presynaptic input, leading to a decrease in excitatory activity at the postsynaptic cell. Therefore, option C is the correct choice. The other options are incorrect; an IPSP (A) or EPSP (D) on the postsynaptic cell can occur due to different mechanisms, and option B is too broad and not specific to the process of presynaptic inhibition.
