Abstract and Keywords
This chapter presents key findings from neuroimaging studies on the neuronal network underlying pain and the affective states. After reviewing the basic concepts and methodological issues relating to research in the field of affective neuroscience, the chapter considers basic negative affective states before turning to basic positive affective states. For each affective state, the chapter analyzes the contribution of neuroimaging studies in elucidating the neuronal mechanisms of the perceptual identification of stimuli related to them, along with the neuronal correlates of the actual experiences (the sentiments) and of the emotional reactions that characterize these affective states. Finally, it discusses the basic neuronal circuitry involved in pain perception in humans and animals as well as the results of neuroimaging studies on pain.
