Kandel and colleagues repeatedly stimulated the tail of an Aplysia with a mild electric shock.They then successfully produced a long-term memory in the Aplysia by demonstrating that the gill:
A)no longer contracted with another tail stimulation conducted a few seconds after the first series of stimulations.
B)contracted after a single tail stimulation conducted days after the repeated stimulations.
C)failed to contract after a single tail stimulation conducted weeks after the repeated stimulations.
D)contracted with each successive tail stimulation conducted seconds apart.

Question

Quizplus · Accepted Answer

The question asks which option demonstrates the successful production of long-term memory in the Aplysia. Option B is the correct answer because it shows that the Aplysia contracted its gill after a single tail stimulation conducted days after the repeated stimulations. This indicates that the Aplysia has formed a long-term memory of the previous stimulation. Options A and D do not indicate the formation of long-term memory because they refer to the immediate response to stimulation. Option C is incorrect because it suggests that the Aplysia has forgotten the previous stimulation, which would not indicate the formation of long-term memory.
