A new study published in the journal Biological Psychiatry found that the habit of smoking can reduce the thickness of the human brain.
Researchers compared the thickness of the cortex on volunteers, both smokers and who had never smoked, who have no medical or psychiatric illness. The cortex is the area of the brain that is responsible for many important functions, including language, information processing, and memory.
The result is stunning. People who smoke thinned cortex in the left middle orbitofrontal. People who smoke more frequently, according to the study, depletion of cortical networks will be increasingly obvious.
These findings show, with thinning of the cortex, then the risk of becoming a drug addict rose, even she will increasingly become heavy smokers.
Because of the thinning, it will be associated with impulse control, reward processing and decision making. This condition may explain how someone can become addicted to nicotine.
