Brain activity prolongs life

Brain activity prolongs life.


Many phrases suggest how emotions sham the body: Loss makes you feel "heartbroken," you suffer from "butterflies" in the stomach when nervous, and gross things make you "sick to your stomach". Now, a new study from Finland suggests connections between emotions and body parts may be insigne across cultures. The researchers coaxed Finnish, Swedish and Taiwanese participants into atmosphere various emotions and then asked them to link their feelings to body parts reloramax. They connected vex to the head, chest, arms and hands; disgust to the head, hands and lower chest; haughtiness 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 activity was the consistency of the ratings, both across individuals and across all the tested argot 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 whosphil com. 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 gather how emotions output and "doesn't show a thing". But for his part, Nummenmaa said the enquire is useful because it sheds light on how emotions and the body are interconnected. "We wanted to understand how the body and the babysit work together for generating emotions. By mapping the bodily changes associated with emotions, we also aimed to see 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 cajole feelings out of the participants by showing them emotive words, stories, clips from movies and facial expressions. Then the participants colored the silhouettes to send the body areas they felt were fit most or least active. The estimation was to not mention emotions directly to the participants but instead to make them "feel assorted emotions".



The researchers noted that some of the emotions may cause activity in specific areas of the body. For example, most principal emotions were linked to sensations in the upper chest, which may have to do with breathing and heart rate. And hoi polloi 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 passion can be misleading since the "areas in the brain that process emotions tend to be mostly outside of our conscious awareness. It would make more sense to directly measure activity in the body, such as agitation and temperature, to make sure people's perceptions have some basis in reality. Nummenmaa said he expects following research to go in that direction.



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