Scientists ID brain regions where nicotine affects attention, cognitive skills

Nicotine administration in humans is known to sharpen attention and to slightly enhance memory. Now scientists, using functional magnetic resonance imaging (MRI), have identified those areas of the brain where nicotine exerts its effects on cognitive skills. Their findings suggest that nicotine improves attention in smokers by enhancing activation in the posterior cortical and subcortical regions of the brain--areas traditionally associated with visual attention, arousal, and motor activation. This study provides the first evidence that nicotine-induced enhancement of parietal cortex activation is associated with improved attention.

Study says nicotine patches effective without direct counseling

Nearly 20 percent of smokers using an over-the-counter nicotine patch in a new study were able to quit smoking entirely after six weeks, compared to only 7 percent of smokers using a dummy patch. Each group reported only mild side effects from patch use, like rashes or insomnia. None of the smokers received any direct instruction on how to use the patch or got behavioral counseling to help them quit smoking, which suggests that nicotine patches used in an over-the-counter manner can be safe and effective, say the study authors. The study was supported by GlaxoSmithKline Consumer Healthcare, which markets the NicoDerm CQ patch.
