Researchers have identified gut microbiota that interact with brain regions associated with mood and behavior. This may be the first time that behavioral and neurobiological differences associated with microbial composition in healthy humans have been identified.

The Hippocampus Underlies the Link Between Slowed Walking and Mental Decline

The connection between slowed walking speed and declining mental acuity appears to arise in the right hippocampus, a finger-shaped region buried deep in the brain at ear-level, according to a 14-year study conducted by scientists at the University of Pittsburgh Graduate School of Public Health.

Study Illuminates Serotonin Contributions to Cocaine’s Allure

A new study reinforces long-held suspicions that the brain chemical serotonin, a molecule usually associated with mood, appetite and libido, makes a direct contribution to the actions of cocaine. Scientists can now clearly see details of how the brain uses serotonin not just to regulate mood, but also to drive both rapid and long-lasting changes in the brain. They suspect these changes may contribute to the brain modifications that ultimately trap users in an addicted state.

Does Religion Protect Against Suicide?

Religious participation is linked to lower suicide rates in many parts of the world, including the United States and Russia, but does not protect against the risk of suicide in sections of Europe and Asia, finds new research by a Michigan State University scholar.

Researchers Examine Brain Region That Affects Drug Use Habits

University of Iowa researchers have identified a brain region involved in cocaine addiction. The findings could lead to targeted drugs or improved behavioral treatments for substance addiction, including opioid dependency. Findings published in the Journal of Neuroscience.

Military Sexual Trauma Among Men Is Prevalent and Predicts Alcohol Problems Years Later

Military sexual trauma (MST) is defined as sexual harassment and/or sexual trauma experienced during the course of military service. It includes uninvited or unwanted verbal or physical contact of a sexual nature, such as attention, verbal remarks, touching, sexual coercion, sexual assault, and rape. It happens to both men and women, and can have not only mental and physical but also behavioral health consequences such as substance use/abuse. Recent findings will be shared at the 40th annual scientific meeting of the Research Society on Alcoholism (RSA) in Denver June 24-28.
