Brain Development Goes Awry As Vulnerable Individuals Develop Schizophrenia

Two new research studies published in Biological Psychiatry point to progressive abnormalities in brain development that emerge as vulnerable individuals develop schizophrenia. One of the studies details the deletion of a small section of chromosome 22, while the other used brain imaging to track brain development in at-risk (for schizophrenia) adolescents over a 10 year […]

Autism-Related Early Brain Overgrowth Confirmed But Found To Slow By Age 2

Scientists using magnetic resonance imaging (MRI) observed that the brains of children with autism spectrum disorder are larger than those without autism, but this difference appears related to increased rates of brain growth before 2 years of age, according to a report in the May issue of Archives of General Psychiatry, one of the JAMA/Archives […]

Integrity Of Brain Reward System Linked To Relapse After Subtance Abuse Treatment

At least 60 percent of individuals treated for an alcohol use disorder will relapse, typically within six months of treatment Given that the brain reward system (BRS) is implicated in the development and maintenance of all forms of addictive disorders, this study compared thickness, surface area, and volume of neocortical components of the BRS among […]

Researchers Explain Why Older People Are Less Astute Drivers And How This Might Improve Evaluation Of Mental Illnesses

When elderly drivers get behind the wheel, they often confront the harrowing reality that they cannot easily see other cars, pedestrians, or cyclists moving around them. This frightening effect of aging, it turns out, is not necessarily a result of a reduced ability to perceive moving objects, as one might suspect, but a heightened awareness […]

Controlling Individual Cortical Nerve Cells By Human Thought

Five years ago, neuroscientist Christof Koch of the California Institute of Technology (Caltech), neurosurgeon Itzhak Fried of UCLA, and their colleagues discovered that a single neuron in the human brain can function much like a sophisticated computer and recognize people, landmarks, and objects, suggesting that a consistent and explicit code may help transform complex visual […]

Brain Imaging (MEG) Test Reveals Hyperactive Brain Network Is Responsible For Involuntary Flashbacks In PTSD

United States scientists have found a correlation between increased circuit activity in the right side of the brain and the suffering of involuntary flashbacks by post-traumatic stress disorder (PTSD) sufferers. The findings, published today, Thursday 28 October, in IOP Publishing’s Journal of Neural Engineering, reveal a clear difference between the communication circuitry of sufferers and […]

Emotion Processing In The Brain Is Influenced By The Color Of Ambient Light

Researchers at the Cyclotron Research Centre (University of Liege), Geneva Center for Neuroscience and Swiss Center for Affective Sciences (University of Geneva), and Surrey Sleep Research Centre (University of Surrey) investigated the immediate effect of light, and of its color composition, on emotion brain processing using functional magnetic resonance imaging. The results of their study […]
