Researchers isolate causes of cognitive loss following coronary artery bypass surgery, finding that minimal aortic movement significantly reduces neurological deficits. The study suggests that emboli are the cause of cognitive problems, and patients who did not use the heart-lung machine had fewer emboli.
A new study by McMaster University found a significant correlation between brain size and intelligence in women. In contrast, men's spatial ability was not strongly related to overall brain size. The study suggests that sex differences may play a role in cognitive processes.
Researchers found that schizophrenic patients lacked gamma band response, indicating defective communication between neurons, while healthy brains showed synchronized activity at 40 hertz. The study suggests that drugs promoting a normal gamma response may help alleviate schizophrenia symptoms.
Scientists have pinpointed the site of a defect in a brain circuit associated with Williams Syndrome, a genetic disorder that affects thinking and cognitive abilities. The study used MRI scans to identify a small region in the brain's white matter that lacked grey matter in people with the disorder.
Researchers used fMRI scans to identify whether participants were imagining faces or places, achieving an accuracy rate of 85% in some trials. The study has implications for understanding the minds of individuals unable to communicate due to injuries or disorders.
