Habituation and sensitization come about because of:
A) a physical connection that forms between two neurons
B) growth of additional neurons
C) changes in neurotransmitter release in the presynaptic neuron
D) changes in neurotransmitter release in the postsynaptic neuron

Question

Quizplus · Accepted Answer

Habituation and sensitization occur due to changes in neurotransmitter release in the presynaptic neuron. Habituation is a decrease in response to a repeated stimulus, and sensitization is an increase in response to a repeated stimulus. Both of these phenomena occur due to changes in the amount or pattern of neurotransmitter release from the presynaptic neuron onto the postsynaptic neuron. There is no physical connection that forms between two neurons or growth of additional neurons, so options A and B are incorrect. Changes in neurotransmitter release in the postsynaptic neuron are not known to be involved in habituation or sensitization, so option D is also incorrect.
