The Effect of Emotions on the Body Mind-Body Connection is Biological

Where Your Body 'Feels' Emotions Revealed In New Study

Scientists have long known that common emotions can trigger sensations in our bodies -- whether it's butterflies in the stomach (anxiety) or hot cheeks (shame). And now a new study suggests that we all have the same bodily sensations associated with our feelings regardless of culture or language -- because the mind-body connection is biological, and is linked to our very drive for survival.

"Our emotional system in the brain sends signals to the body so we can deal with our situation," study leader Dr. Lauri Nummenmaa, assistant professor at Aalto University's School of Science in Finland, told NPR. "Say you see a snake and you feel fear... Your nervous system increases oxygen to your muscles and raises your heart rate so you can deal with the threat. It's an automated system. We don't have to think about it."

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.

None of this is a surprise, its expected by most with training in biology who have ever thought about the mind. Here is something I wrote very recently elsewhere:

The mind. There is no such thing as mind. What we call mind is an emergent phenomena of the brain, though the term "mind" is used as a simplified explanation of what we see and experience, and internal self-talk. Its folklore, but very convenient. I use the term mind a lot, its so very much harder to describe the underlying properties every time you want to mention something connected with mind. There, I did it again. This word is almost ubiquitous.

Nice find Ecoclimber. Would be interesting if the self-reports could be further detailed with some sort of objective scanning.

Of course the mind-body connection is biological though, it is not magic afterall.

Doesn't this just demonstrate cultural/human biases? We are subconsciously taught to make certain associations and then report such on questionnaires when studied.
