This chapter has a different view of the role of the amygdala in information storage from that in the previous chapter. This issue was addressed in a recent commentary and by the experimental studies of Vazdarjanova and McGaugh. Later, this chapter suggests that it cannot be excluded that the amygdala has both a modulatory and a storage function. If anything, this discussion illustrates the difficulties involved in the localizing function in the field of learning and memory. An alternative approach to the study of the neural mechanisms of learning and memory is to formulate the processing requirements for a system that could subserve information storage, and to construct a model on the basis of these requirements. Numerous such modeling attempts employ the principles of parallel distributed processing, in which the strength of connections between units in multilayered networks represents stored information.

Keywords:   amygdala, neural mechanisms, learning and memory, parallel distributed processing, multilayered networks
