Aplysia have been used to study the physiological properties of learning because:
A) they only have one neuron, which makes it easy to see and study
B) they only have a few neurons, which are relatively large in size
C) they have the same number of neurons as humans, so generalizations can be made from Aplysia to humans
D) none of the above

Question

Quizplus · Accepted Answer

Aplysia have relatively simple nervous systems consisting of only a few large neurons, making them ideal for studying the cellular and molecular mechanisms of learning and memory. However, they do not have only one neuron, as option A suggests, and they have significantly fewer neurons than humans, making it difficult to generalize findings to humans as suggested in option C.
