Most of the genetic risk for developing a substance use disorder comes from genes that broadly affect how our brains process rewards, regulate impulses and weigh consequences—not from genes that ...

Researchers from the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) report that the gene, CHRNA3, acts as a key regulator of alcohol sensitivity. Published in ...

Genes tied to impulse control, reward processing and risk‑taking play a larger role in addiction risk than genes linked to any single drug, according to a major new Rutgers‑led study. Analyzing ...

Researchers at the University of California San Diego have completed a massive genetic study that identifies key biological drivers of cocaine addiction, uncovering a potential new target for ...

About 1 in 5 individuals develop a substance use disorder; more than 46 million people in the United States are affected at any given time. And yet, most people choose to use alcohol or other drugs ...

Researchers have found a unique molecular signature and genes in the orbitofrontal cortex associated with heroin-seeking behavior. A preclinical rodent model implicated a gene called Shisa7 as the key ...

This post is in response to Self-confidence: Less self-generated than you notice until you're unemployed By Jeremy E. Sherman Ph.D. Evolutionary psychology generally focuses on the ways in which ...

A Rutgers-led study found that genes related to impulse control and reward processing are major factors in addiction risk. Researchers analyzed genetic data from over 2.2 million people to understand ...
