Different brain areas linked to smoking and drinking

Academics at the University of Warwick have found that low functional connectivity of the lateral orbitofrontal cortex that is associated with the tendency to smoke is associated with increased impulsiveness — which may contribute to the tendency to smoke. The high connectivity of the reward-related medial orbitofrontal cortex in drinkers may increase the tendency to

Scientists map interactions between head and neck cancer and HPV virus: Connecting the dots between human papillomavirus and smoking-related cancers

Human papillomavirus (HPV) is widely known to cause nearly all cases of cervical cancer. However, you might not know that HPV also causes 70 percent of oropharyngeal cancer, a subset of head and neck cancers that affect the mouth, tongue, and tonsils. Although vaccines that protect against HPV infection are now available, they are not

Nicotine alters neurotransmission in habit-forming brain region: Nicotine reduces dorsal striatal output, which may underlie urge to smoke and make it difficult to break the habit

A study of rat brain slices published in JNeurosci demonstrates how nicotine interacts with cells that regulate the output of a brain region involved in habit formation. The research could inform efforts to help people quit smoking and avoid relapse. The addictive qualities of nicotine have been attributed to the brain’s reward system. However, recent
