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...

Microbial Based Treatment Reverses ASD’s Social Deficits: Mouse Study

Researchers report the administration of Lactobacillus reuteri may lead to brain changes that reverse social deficits in mouse models of ASD through a mechanism that involves the vagus nerve and reward system. The findings hold promise for the development of treatments for ASD, as well as other disorders, by modulating specific gut microbes.... Read More...
