Activity Of Individual Brain Cells Predicts Cognitive Flexibility A new study provides intriguing insights into mechanisms of cognitive flexibility at the single cell level. The research may help to explain how we can change our point of view when faced with conflict.
Brain Cells Have 'Memory', Researcher Discovers As we look at the world around us, images flicker into our brains like disparate pixels on a computer screen that change several times a second. Yet we don't perceive the world as a constantly flashing computer display. Why not? Neuroscientists think that part of the answer lies in a special region of the brain's visual cortex which is in charge of distinguishing between background and foreground
Brain Works Best When Cells Keep Right Rhythms, New Studies Suggest New research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning. These rhythms don't appear to be working correctly in such diseases as schizophrenia and autism, and now Nature and Science demonstrate that precisely tuning the oscillation frequencies of certain neurons can affect how the brain processes information and implements feelings of r
Autism Genes Discovered; Help Shape Connections Among Brain Cells Scientists have connected more of the intricate pieces of the autism puzzle, with two studies that identify genes with important contributions to the disorder. One study pinpoints a gene region that may account for as many as 15 percent of autism cases, while another study identifies missing or duplicated stretches of DNA along two crucial gene pathways. Significantly, both studies detected genes
Human Brain Can Recognize Objects Much Faster Than Some Have Thought Some experts believe that vision isn't possible without feedback from higher levels of the brain, but a study now demonstrates that the brain can rapidly recognize objects under a variety of conditions at a very early processing stage. The study involved patients with epilepsy who were undergoing high-resolution brain mapping prior to neurosurgery.
