Document Summary

Most writers had argued that the experience of an emotion is a response to an emotionally exciting event. Emotional experience in turn generates emotion-related bodily changes, including actions. James altered this sequence, and he located the origins of emotional experience in the body. For him the sequence was: (a) exciting event, (b) bodily responses to the event, (c) perception of these bodily responses as the experience of emotion: controversial thesis. James contended that every emotion involves a distinct bodily reverberation in the glands that make up the neuroendocrine system, in the autonomic nervous system, and in muscles by which action is produced. Neural signals from the cortex communicate with the limbic system and the hypothalamus, which send signals to clusters of neurons of the autonomic nervous system and target organs, glands, muscles, and blood vessels. These structures in turn send signals back via the autonomic nervous system to the hypothalamus, limbic system, and cortex.
