Scientists hunt down the brain circuit responsible for alcohol cravings: Study may open the door to developing drug therapies or even gene therapies for alcohol addiction

Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats — with the flip of a switch. The researchers were able to use lasers to temporarily inactivate a specific neuronal population, reversing alcohol-seeking behavior and even reducing the physical symptoms of withdrawal. “This discovery is exciting — it

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

Journalism study evaluates emotions on the job

A QUT journalism academic says the current freelancer-heavy market for media professionals could be preventing photographers and video journalists who report on traumatic news events from accessing the support they need. The results of TJ Thomson’s peer-reviewed study Mapping the emotional labor and work of visual journalism has been published in Journalism. “People understand exposure

Adolescent binge drinking disrupts mouse memory in adulthood: Study could help scientists better understand development of alcohol use disorders in adults

Excessive drinking during adolescence may interfere with the activity of brain cells needed for sustaining short term memory, according to new research in adolescent male mice published in JNeurosci. The study could help scientists better understand the development of alcohol use disorders in adults. The prefrontal cortex (PFC) and the behavior-management abilities it supports —

Magnetic stimulation dampens brain response to drug cues in addiction

In a study investigating the use of transcranial magnetic stimulation (TMS) for drug addiction, researchers at Medical University of South Carolina are the first to demonstrate that the noninvasive brain stimulation technique can dampen brain activity in response to drug cues in chronic alcohol users and chronic cocaine users. The findings are published in Biological

Alcoholic Drinks Kill Good Mouth Bacteria but Leave the Bad

A new study found the mouths of drinkers contained more bad bacteria that potentially cause disease. There’s no lack of evidence that drinking too much alcohol is bad for you. But here’s one more reason to cut down: teeth. A recent article published in Microbiome last month found, in a large study of American adults,
