Computational Model Sheds Light On How The Brain Recognizes Objects

Researchers at MIT’s McGovern Institute for Brain Research have developed a new mathematical model to describe how the human brain visually identifies objects. The model accurately predicts human performance on certain visual-perception tasks, which suggests that it is a good indication of what actually happens in the brain, and it could also help improve computer […]

Adolescent Brains Biologically Wired To Engage In Risky Behavior

There are biological motivations behind the stereotypically poor decisions and risky behavior associated with adolescence, new research from a University of Texas at Austin psychologist reveals. Previous studies have found that teenagers tend to be more sensitive to rewards than either children or adults. Now, Russell Poldrack and fellow researchers have taken the first major […]

Deep Brain Stimulation At Two Different Targets Produces Similar Motor Improvements in Parkinson’s Disease

In a major study, investigators have compared how individuals with Parkinson’s disease respond to deep brain stimulation (DBS) at two different sites in the brain. Contrary to current belief, patients who received DBS at either site in the brain experienced comparable benefits for the motor symptoms of Parkinson’s. The results appear in the June 3, 2010 issue of the New England Journal of Medicine.

Meditation Reduces The Emotional Impact Of Pain

People who meditate regularly find pain less unpleasant because their brains anticipate the pain less, a new study has found. Scientists from The University of Manchester recruited individuals into the study who had a diverse range of experience with meditation, spanning anything from months to decades. It was only the more advanced meditators whose anticipation […]

Blood Flows Differently Through The Brains Of Schizophrenic Patients

Researchers in Germany have used a magnetic resonance imaging (MRI) technique called continuous arterial spin labeling (CASL) to map cerebral blood flow patterns in schizophrenic patients quickly and without using radiation or contrast agents. Their findings appear in the online edition and July printed issue of the journal Radiology.

Education Helps Protect Against Dementia

Researchers have discovered that education not only delays the early symptoms of dementia, but can also slow down the development of the disease – a finding that could result in faster diagnosis and treatment of dementia, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. Previous studies have shown that education […]
