Brain activity prolongs life

Brain activity prolongs life.


Many phrases reproduce how emotions attack the body: Loss makes you feel "heartbroken," you suffer from "butterflies" in the stomach when nervous, and repellent things make you "sick to your stomach". Now, a new study from Finland suggests connections between emotions and body parts may be archetype across cultures. The researchers coaxed Finnish, Swedish and Taiwanese participants into vehemence various emotions and then asked them to link their feelings to body parts health. They connected annoy to the head, chest, arms and hands; disgust to the head, hands and lower chest; snobbishness to the upper body; and love to the whole body except the legs.



As for anxiety, participants heavily linked it to the mid-chest. "The most surprising dislike was the consistency of the ratings, both across individuals and across all the tested idiolect groups and cultures," said study lead author Lauri Nummenmaa, an aide-de-camp professor of cognitive neuroscience at Finland's Aalto University School of Science herbal bud. However, one US expert, Paul Zak, chairman of the Center for Neuroeconomics Studies at Claremont Graduate University in California, was unimpressed by the findings.



He discounted the study, saying it was weakly designed, failed to discern how emotions pan out and "doesn't establish a thing". But for his part, Nummenmaa said the inspect is useful because it sheds light on how emotions and the body are interconnected. "We wanted to understand how the body and the take offence at work together for generating emotions. By mapping the bodily changes associated with emotions, we also aimed to realize how different emotions such as disgust or sadness actually govern bodily functions".



For the study, published online Dec 30, 2013 in Proceedings of the National Academy of Sciences, the researchers showed two silhouettes of bodies to about 700 people. Depending on the experiment, they tried to persuade feelings out of the participants by showing them hotheaded words, stories, clips from movies and facial expressions. Then the participants colored the silhouettes to exemplify the body areas they felt were stylish most or least active. The teaching was to not mention emotions directly to the participants but instead to make them "feel peculiar emotions".



The researchers noted that some of the emotions may cause activity in specific areas of the body. For example, most primary emotions were linked to sensations in the upper chest, which may have to do with breathing and heart rate. And folk linked all the emotions to the head, suggesting a possible link to brain activity. But Zak said the inquiry failed to consider that people often feel more than one emotion at a time.



Or that a person's own comprehension of sensation can be misleading since the "areas in the brain that process emotions tend to be on the whole outside of our conscious awareness. It would make more sense to directly measure activity in the body, such as glow and temperature, to make sure people's perceptions have some basis in reality. Nummenmaa said he expects coming research to go in that direction.



How might the current research be useful? Zak is skeptical that it could be, but the look lead author is hopeful. "Many mental disorders are associated with altered functioning of the highly-strung system, so unraveling how emotions coordinate with the minds and bodies of healthy individuals is conspicuous for developing treatments for such disorders. Next, the researchers want to see if these emotion-body connections change in populace who are anxious or depressed brightening. "Also, we are interested in how children and adolescents experience their emotions in their bodies".

before.
