According to Eric Kandel and his colleagues,sensitization in Aplysia results from
A) reduced responsiveness of sensory neurons.

C) increased input to motor neurons serving the gill.
D) decreased input to motor neurons serving the gill.

Question

Quizplus · Accepted Answer

Sensitization in Aplysia results from increased input to motor neurons serving the gill. This is due to the release of serotonin by interneurons activated by noxious stimuli. The serotonin binds to receptors on sensory neuron terminals and enhances the release of neurotransmitter onto motor neurons, resulting in stronger and more prolonged gill contractions.
