Question

Quizplus · Accepted Answer

Classical conditioning involves the association of a neutral stimulus with a meaningful stimulus, leading to a learned response. In Aplysia, this type of learning is associated with an increase in serotonin release at certain synapses, specifically those involved in the gill-withdrawal reflex. This neurotransmitter release results in changes in the strength of the synapses involved in the reflex, leading to enhanced responsiveness to the conditioned stimulus.
