Research with the Sea Snail Aplysia Has Demonstrated That

Research with the sea snail Aplysia has demonstrated that:

A) the sea snail's nervous system is too primitive to form memories.
B) long-term potentiation is only possible in animals with more sophisticated and complex nervous systems.
C) forming a new memory involves changes in both the function and structure of neurons.
D) anterograde and retrograde amnesia involve fundamentally different neural circuits.
