A combination of brain scans and reading tests has revealed that several regions in the brain are responsible for allowing humans to read. The findings open up the possibility that individuals who have difficulty reading may only need additional training for specific parts of the brain — targeted therapies that could more directly address their individual weaknesses.
Children with Asperger’s syndrome show patterns of brain connectivity distinct from those of children with autism, according to a new study.
Scientists have discovered that the brain circuits we engage when we think about social matters, such as considering other people’s views, or moral issues, inhibit the circuits that we use when we think about inanimate, analytical things, such as working on a physics problem or making sure the numbers add up when we balance our budget. And they say, the same happens the other way around: the analytic brain network inhibits the social network.
Using direct human brain recordings, a research team has identified a new type of cell in the brain that helps people to keep track of their relative location while navigating an unfamiliar environment.
A collaborative team of researchers has uncovered evidence
that a specific genetic alteration appears to contribute to disorders of brain development, including schizophrenia. They also found that schizophrenia shares a common biological pathway with Fragile X mental syndrome, a disorder associated with both intellectual impairment and autism.
A team of researchers has identified 18 new genes responsible for driving glioblastoma multiforme, the most common—and most aggressive—form of brain cancer in adults. The study was published August 5, 2013, in Nature Genetics.
Johns Hopkins biophysicists have discovered that full activation of a protein ensemble essential for communication between nerve cells in the brain and spinal cord requires a lot of organized back-and-forth motion of some of the ensemble’s segments. Their research, they say, may reveal multiple sites within the protein ensemble that could be used as drug targets to normalize its activity in such neurological disorders as epilepsy, schizophrenia, Parkinson’s and Alzheimer’s disease.
A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study from UC Berkeley that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity
