C)decrease in the number of sensory neurons.
D)increase in the number of motor neurons.

Question

Quizplus · Accepted Answer

Sensitization in aplysia results from an increase in glutamate released from the sensory neurons. This increased release of glutamate can lead to the activation of interneurons, which in turn activate motor neurons and result in a heightened response to a previously neutral or sub-threshold stimulus. Decreasing glutamate release or the number of sensory neurons would not lead to sensitization, and increasing the number of motor neurons alone would not result in sensitization without also increasing glutamate release from the sensory neurons.
