Brain activity may help determine a desire to stop smoking

The activity of the brain may help assess the determination of a smoker to quit, according to a study by researchers who observed scanned region of cortex related to changes in behavior.

The study, published in the journal Health Psychology, involved 28 heavy smokers who joined a program to switch off the cigarette.

Participants have been invited to watch a series of messages about stopping smoking while a scanner was recording the activity of their brains.

After each message, the patients noted how it had affected their plans of stopping smoking and if this had reinforced their determination to do it.

People whose cortex activity showed a higher activity for messages were "significantly" more likely to reduce their consumption of cigarettes in the next month.

"What's exciting is that knowing what happens in the brain of someone can better predict his future behavior as if we knew his own valuation", which shows his chances of stopping smoking, Analysis Emily Falk, lead author of the study and director of the Neuroscience Laboratory and the Communication University of Michigan said.
