We begin by focusing on sensitization, an elementary form of nonassociative learning by which an animal learns about the properties of a single noxious stimulus and enables the formation of a learned fear response.
Such examples of nonassociative learning mechanisms have led scientists to argue that there is no unitary learning process at the computational level of analysis.

Moreover, recent evidence indicates that not only associative learning, but also nonassociative learning, in Aplysia depends critically on postsynaptic changes.
The recent work on nonassociative learning in Aplysia suggests that postsynaptic processes play critical roles in both habituation and sensitization.
