The amygdala is a fascinating complex structure that lies at the center of much of our current thinking about emotion Here I will review data that suggest that the amygdala is involved in several processes linked to determining what a stimulus is and what the organism should therefore do - the two questions that are part of the title This piece will focus on three main aspects of amygdala function namely attention value representation and decision making by reviewing both non-human and human data Two mechanisms of affective attention will be described The first involves projections from the central nucleus of the amygdala to the basal forebrain which has extensive and diffuse projections throughout the cortical mantle The second Involves projections from the basal amygdala to multiple levels across the visual cortex I will also describe how the basolateral amygdala is important for the representation of value and in decision making Overall it will be argued that the amygdala plays a key role in solving the following problem How can a limited-capacity information processing system that receives a constant stream of diverse inputs be designed to selectively process those inputs that are most significant to the objectives of the system? What is it? and What s to be done? processes can then be viewed as important building blocks in the construction of emotion a process that is intertwined with cognition Furthermore answering the two questions directs how resources should be mobilized as the organism seeks out additional information from the environment (C) 2010 Elsevier Ltd All rights reserved
