内容説明
The monograph aims to present the recent scientific knowledge on body sensations, i.e., conscious experiences that are localized or felt in the body from an internal perspective, regardless of their sensory origin. It summarizes the basic philosophical, evolutionary, neuroanatomical, psychological, and pathological aspects of the topic. Moreover, related phenomena, such as emotions, the placebo and nocebo effect, complementary and alternative medicine, and mind-body practices are discussed from the perspective of body sensations.
