Old Habit-Controlling Neurons May Also Help the Brain Learn New Tricks

In a study of rodents, scientists at the Icahn School of Medicine at Mount Sinai discovered that a part of the brain traditionally thought to control typing the old habits may also play a critical role in learning the new actions. The results, published on August 25th in Nature Communications, suggest that this process involves a delicate balance in the activity of two neighboring neural circuits: one dedicated to new actions and the other to old habits

Experts caution: vaping prevention critical as teens head back to school during ongoing pandemic

Newswise imageThe global COVID-19 pandemic has forced many people to live in relative isolation for more than a year. As adolescents return to school, public health experts caution parents to pay close attention to signs of tobacco use among teens.

Experts express concern about rising rates of dual- and poly-tobacco product use, particularly among adolescents and young adults. A new evidence-based research centerThe evidence-based tobacco research program is conducting collaborative research aimed at increasing scientific knowledge to help regulate tobacco products effectively in a way that best serves individual and public health interests.

Recovery From Alcohol Use Disorder: Long-term Abstinence Accompanied by Brain Changes and Emotional Improvements

from alcohol use disorder (AUD) have been clarified in a new study in Alcoholism: Clinical and Experimental Research. AUD recovery was already known to be multidimensional, with behavioral changes – ranging from stopping heavy drinking to complete abstinence – accompanied by partial reversal of alcohol-induced brain damage. While the relationship between early abstinence (the “withdrawal phase”), negative mood, and sex-specific effects of alcohol on the brain’s “reward system” have been well-established, a growing body of evidence is revealing that AUD individuals in long-term abstinence (greater than five years) report higher levels of subjective happiness and emotional well-being, as well as a significantly lower risk of relapse. Yet, the way these long-term behavioral and emotional improvements relate to underlying brain changes, and potentially differ between men and women, remains unknown. To better understand and characterize these aspects of the recovery process, the study’s res

Co-locating Contraceptive Services & Opioid Treatment Programs May Help Prevent Unintended Pregnancy

More than 75% of women with Opioid Use Disorder report having had an unintended pregnancy, but they are less likely to use effective contraception compared to women who do not use drugs. Results from a multi-year trial found that a two-part intervention featuring co-located contraceptive services in opioid treatment programs and financial incentives could offer an effective solution.
