For this reason, the present chapter will highlight the basic assumptions that underlie these methodologies. The assumption that behavior is localized in the brain underlies the need for imaging methods in psychology. But these methods are only as good as the information they provide. Accordingly, we start with a review of the relation between neural activity and metabolism in the brain, and then proceed to describe the relation between blood flow and ...
