Kandel and Colleagues Stimulated the Tail of an Aplysia with a Mild

Kandel and colleagues stimulated the tail of an Aplysia with a mild electric shock, which caused contraction of its gill. They then successfully produced a long-term memory in the Aplysia by demonstrating that gill contraction speed changed:

A) after a second tail stimulation conducted a few seconds after the first stimulation.
B) after a single tail stimulation conducted days after repeated stimulations.
C) after a second tail stimulation conducted days after the first stimulation.
D) with each successive tail stimulation conducted seconds apart.
