This chapter reviews recent work on human imaging of memory. Essentially, functional magnetic resonance imaging and positron emission tomography are scanning methods that visualize regional increases in blood flow or oxygen or glucose metabolism. Thus, they are a measure of neural activation during certain behavioural tasks in awake humans. First, this chapter shows that the amygdala is activated in aversive conditioning. The second paradigm that is investigated is priming, which is a facilitation of recognition or production of a stimulus by prior exposure to a stimulus with which the recognized item has a relationship of physical similarity or associated meaning. Priming involves activation of the right or left fusiform gyrus for faces and objects, respectively. The fusiform gyrus is in the inferior temporal cortex, caudal to perirhinal cortex.

Keywords:   magnetic resonance imaging, positron emission tomography, neural activation, amygdala, priming
