How Your Brain Could Keep You from Quitting


I’m Shelby Cullinan with today’s health news.
Many have tried, but not all have succeeded.
And as it turns out, the attempt to quit smoking
may have a little something to do with your
brain chemistry. A new study found that those
who have an easier time kicking the habit
tended to have stronger connections between
the region of the brain that acknowledges
rewards and that which controls impulsive
behavior. The authors of this study looked
at the brains of 85 heavy smokers, studying
activity via functional magnetic resonance
imaging,or fMRI. Those with the better connections
between the two brain regions were more likely
to successfully quit smoking for 10 weeks.
Researchers were particularly interested in
an area deep within the brain known as the
insula. They believe this area serves as a
bridge between two parts of the brain that
may play a central role in regulating addictive
behaviors. In theory, the insula could be
targeted by treatments designed to help patients
quit smoking.
