Emotions and Olfaction

Abstract

Abstract This chapter provides a comprehensive overview linking the sense of smell to the field of emotion. The authors focus on the evolution of the olfactory system and its anatomical pathways, including overlapping structures with emotional processing circuits. The chapter proceeds with a detailed analysis of the functional relationship between olfaction and emotion based on the following topics: odors and leading emotional reactions; odors as chemosignals within social communication (focusing on a definition of chemosignals; chemosignals and emotional contagion; and chemosignals within intimate relationships); and odors as a basis for multisensory integration in the context of emotional processing. Throughout the chapter, the authors present a broad range of experimental studies including behavioral and neuroimaging investigations, as well as implications of research on patients with olfactory deficits.
