In sensitization in Aplysia, what processes account for the stronger than normal responses of gill motor neurons?
A) extended action potentials in siphon sensory neurons, which result in the release of greater than normal amounts of neurotransmitter at synapses with gill motor neurons.
B) extended action potentials in siphon sensory neurons, which result in the release of less than normal amounts of neurotransmitter at synapses with gill motor neurons.
C) shortened action potentials in siphon sensory neurons, which result in the release of greater than normal amounts of neurotransmitter at synapses with gill motor neurons
D) shortened action potentials in siphon sensory neurons, which result in the release of less than normal amounts of neurotransmitter at synapses with gill motor neurons.

Question

Quizplus · Accepted Answer

Sensitization in Aplysia involves an extended action potential in the siphon sensory neurons, which leads to the release of greater than normal amounts of neurotransmitter (serotonin) at synapses with gill motor neurons. This results in stronger than normal responses of the gill motor neurons, which is the hallmark of sensitization.
