NIDA News - Vulnerabilities Revealed in Resting Brain Posted By: David Kennedy - Dec 22, 2011Tool/Resource: NITRC Community Resting Brain Studies Shed New Light on Vulnerabilities NIDA Research Findings Vol. 24, No. 1 (November 2011) Brain circuits that remain active when individuals are resting provide clues to what goes awry in addiction and other mental disorders. By LORI WHITTEN, NIDA Notes Staff Writer Findings from a recent NIDA-funded study represent early fruits of research on a recently recognized network of brain circuits. Dr. Elliott Hong and colleagues at the University of Maryland School of Medicine and collaborators at the NIDA Intramural Research Program showed that the strength of one of these "resting-state" circuits correlates with individuals' vulnerability to nicotine dependence. Moreover, this circuit appears to mediate the increases in dependence associated with an important genetic risk factor. See http://www.drugabuse.gov/NIDA_notes/NNvo... for complete article. |
