That's
Why They're Called Feelings

WASHINGTON -- Maybe a broken heart really
does hurt. A new study suggests evidence for an old idea ... that
emotions aren't just expressions of the mind, but rather a series
of palpable sensations.
Researchers at the University of Iowa College
of Medicine looked at brain scans of 41 test subjects who were recalling
emotional events indicated activity in areas of the brain not normally
associated with emotions, but rather with monitoring body function.
The concept, which has been around for more than a century, suggests
emotions trigger certain changes in the body, which the brain then
monitors and interprets according to the stimulus.
According to researchers, the subjects "recalled
and re-experienced personal life episodes marked by sadness, happiness,
anger or fear," while researchers used brain scans and other
sensors to monitor the physical activity produced by those sensations.
The scans appeared to demonstrate that each emotion caused a different
pattern of brain activity; the study results seem to lend credence
to the idea that emotions, far from being a subjective entity, have
a physiological basis.
Lead
researcher, Antonio Damasio, wrote a book in 1999 titled "The
Feeling of What Happens" which expands on the old idea. The
brain scan results, he says, support the premise with hard data.
Researchers suggest the study may also lead to better drugs for
treating mental conditions like depression.
