Excessive, chronic drinking can cause brain damage leading to the development of emotional abnormalities that can interfere with healthy interpersonal relationships. Alcoholism-related emotional abnormalities can be subtle, such as misperceiving facial and verbal cues, or obvious, such as emotional flatness and apathy or sudden outbursts of anger. "Alcoholics also have problems in judging the emotional expressions on people's faces," Ksenija Marinkovic, assistant professor in residence in the...

 Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others. The findings, which appear in the August 11 issue of Alcoholism: Clinical and Experimental Research, confirms that alcoholics suffer from abnormalities in parts of the brain that control emotional perception and...

Fear is a powerful emotion and neuroscientists have for the first time located the neurons responsible for fear conditioning in the mammalian brain. Fear conditioning is a form of Pavlovian, or associative, learning and is considered to be a model system for understanding human phobias, post-traumatic stress disorder and other anxiety disorders.Using an imaging technique that enabled them to trace the process of neural activation in the brains of rats, University of Washington researchers...

U.S. scientists say an automated measure of brain volume may help predict progression to Alzheimer's disease. The procedure -- volumetric magnetic resonance imaging -- measures the memory centers of the brain and compares them to expected size. The study, published in Alzheimer's Disease and Associated Disorders, examined the fully automated volume measures of 269 patients with mild cognitive impairment over a six-month interval. Dr. Michael Rafii of the University of California in San...

New, automated way of measuring brain structures appears effective in predicting progression to Alzheimer's DiseaseScientists at the University of California, San Diego School of Medicine have shown that a fully automated procedure called Volumetric MRI "“ which measures the "memory centers" of the brain and compares them to expected size "“ is effective in predicting the progression from mild cognitive impairment (MCI) to Alzheimer's disease. The procedure can be readily used in...

Autistic toddlers appear more likely to have an enlarged amygdala, a brain area associated with processing faces and emotion, U.S. researchers suggest. Matthew W. Mosconi and colleagues at the University of North Carolina at Chapel Hill say this brain abnormality appears to be associated with the ability to share attention with others -- a fundamental ability thought to predict later social and language function in children with autism. The researchers conducted a magnetic resonance imaging...

Toddlers with autism appear more likely to have an enlarged amygdala, a brain area associated with numerous functions, including the processing of faces and emotion, according to a report in the May issue of Archives of General Psychiatry, one of the JAMA/Archives journals. In addition, this brain abnormality appears to be associated with the ability to share attention with others, a fundamental ability thought to predict later social and language function in children with autism. "Autism is...

Disrupting a brain protein produces antidepressant-like effect in mice A brain protein involved in fear behavior and anxiety may represent a new target for depression therapies, according to a study by researchers at the University of Iowa and the Iowa City Veterans Affairs Medical Center. The results appear in the April 29 issue of the Journal of Neuroscience. Depression affects at least 14 million American adults and can be severely disabling. However, the causes of depression are not well...

Women who had been depressed have different brain patterns than the never-depressed when hearing a mother's criticism, U.S. researchers said. Study leader Jill Hooley of Harvard University in Boston said formerly depressed women show patterns of brain activity when they are criticized by their mothers that are distinctly different from the patterns shown by never-depressed controls. The study, published in Psychiatry Research: Neuroimaging, had 23 female participants -- 12 who had no history...

U.S. neuroscientists say they have identified the brain's neural systems that are involved in forming first impressions of people. The New York University and Harvard University researchers say their findings show how we encode social information and then evaluate it in making such initial judgments. The scientists said they sought to investigate the brain mechanisms that give rise to impressions formed immediately after meeting a new person. They designed an experiment in which they used...
