The mechanisms for classical conditioning in Aplysia involve _____ changes in the neural circuits that connect the _____.
A) presynaptic; CS and UR
B) postsynaptic; CS and UR
C) presynaptic and postsynaptic; CS and UR
D) presynaptic and postsynaptic; CS and CR

Question

Quizplus · Accepted Answer

Classical conditioning in Aplysia involves both presynaptic and postsynaptic changes in the neural circuits that connect the conditioned stimulus (CS) and the conditioned response (CR), not the unconditioned response (UR). This is because the learning process modifies the strength and efficiency of synaptic connections to produce a new or altered response to a previously neutral stimulus.
