Different Brain Areas Linked to Smoking and Drinking Behaviors
A new study reveals researchers have identified areas of the brain which are different in those who regularly smoke and drink alcohol. Researchers discovered the medial orbitofrontal cortex, an area of the brain implicated in reward, has higher functional connectivity in drinkers. In those who smoke, the lateral orbiotfrontal cortex, an area of the brain linked to impulsive behavior, has lower functional connectivity. The study suggests nicotine may increase overall brain connectivity, which may lead to increased smoking behaviors. ... Read More...
Higher Levels of Nicotine May Help Smokers Quit
Researchers report allowing smokers to dictate their nicotine intake while trying to quit makes them more likely to succeed. Results suggest most smokers who use nicotine replacement medications can tolerate doses that are four times higher than normally recommended.... Read More...
Making Mice Lose Weight by Imitating Effects From Cold and Nicotine
