Years ago, children were warned that smoking could stunt their growth, but now a major study by an international team including the Montreal Neurological Institute at McGill University and the University of Edinburgh shows new evidence that long-term smoking could cause thinning of the brain’s cortex. The cortex is the outer layer of the brain in which critical cognitive functions such as memory, language and perception take place. Interestingly, the findings also suggest that stopping smoking helps to restore at least part of the cortex’s thickness.

January 29, 2013 - Addiction to cigarettes, drugs and other stimulants has been linked in the past to the brain’s frontal lobes, but now there is scientific evidence that indicates where in the frontal cortex addiction takes hold and how.  Addiction could be a result of abnormal communication between two areas of the frontal lobes linked to decision-making.  The discovery will undoubtedly stimulate clinical work on new therapies for millions of people who suffer from addiction.
