Bodily maps of emotions
TLDR
It is proposed that emotions are represented in the somatosensory system as culturally universal categorical somatotopic maps, and maps of bodily sensations associated with different emotions using a unique topographical self-report method.Abstract:
Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. Here we reveal maps of bodily sensations associated with different emotions using a unique topographical self-report method. In five experiments, participants (n = 701) were shown two silhouettes of bodies alongside emotional words, stories, movies, or facial expressions. They were asked to color the bodily regions whose activity they felt increasing or decreasing while viewing each stimulus. Different emotions were consistently associated with statistically separable bodily sensation maps across experiments. These maps were concordant across West European and East Asian samples. Statistical classifiers distinguished emotion-specific activation maps accurately, confirming independence of topographies across emotions. We propose that emotions are represented in the somatosensory system as culturally universal categorical somatotopic maps. Perception of these emotion-triggered bodily changes may play a key role in generating consciously felt emotions.read more

TL;DR: Brain regions contributing most to the classification accuracy included medial and inferior lateral prefrontal cortices, frontal pole, precentral and postcentral gyri, precuneus, and posterior cingulate cortex, suggesting a direct link between activity in these brain regions and the subjective emotional experience.

TL;DR: The results indicate an origin of emotion deficits and affective symptoms in ASC at the interface between body and mind, specifically in expectancy-driven interpretation of interoceptive information.

An argument for basic emotions
TL;DR: This work has shown that not only the intensity of an emotion but also its direction may vary greatly both in the amygdala and in the brain during the course of emotion regulation.

TL;DR: The hypothesis rejects attempts to limit human reasoning and decision making to mechanisms relying, in an exclusive and unrelated manner, on either conditioning alone or cognition alone.

TL;DR: A model of empathy that involves parallel and distributed processing in a number of dissociable computational mechanisms is proposed and may be used to make specific predictions about the various empathy deficits that can be encountered in different forms of social and neurological disorders.
