Stress and addiction: contribution of the corticotropin releasing factor (CRF) system in neuroplasticity (2012)

Front Mol Neurosci. 2012; 5: 91. Published online 2012 September 6. doi:  10.3389/fnmol.2012.00091 Carolina L. Haass-Koffler1,2 and Selena E. Bartlett1,3,* Abstract Corticotropin releasing factor (CRF) has been shown to induce various behavioral changes related to adaptation to stress. Dysregulation of the CRF system at any point can lead to a variety of psychiatric disorders, including […]

Structural and functional abnormalities found in brains of relapsed alcohol-dependent patients (2012)

COMMENTS: Unique study, which shows that relapse caused specific brain changes in the regions associated with impulse control and decision making (frontal lobes) September 20th, 2012 in Psychology & Psychiatry Scientists at Charité – Universitätsmedizin Berlin have succeeded in coming closer to determining the risk of relapse in detoxified alcohol-dependent patients. Using an imaging process […]
