How Does the Brain Respond to Texture?

The human hands and fingertips are extremely sensitive to texture or surface microstructure, which can easily perceive the finest details of a surface’s characteristics. The nerve signals sent from the sensors in the hand skin are processed by several neurons in the somatosensory cortex to produce a high-dimensional representation of texture in the brain.

New study finds evidence for reduced brain connections in schizophrenia

Advances in scanning have allowed researchers for the first time to show lower levels of a protein found in the connections between neurons in the living brains of people with schizophrenia. The researchers, who conducted the scans at the psychiatric imaging facility at the Medical Research Council (MRC) London Institute of Medical Sciences, say these changes could underlie the cognitive […]

Peering into the genome of brain tumor

Researchers at Osaka University have developed a computer method that uses magnetic resonance imaging (MRI) and machine learning to rapidly forecast genetic mutations in glioma tumors, which occur in the brain or spine. The work may help glioma patients to receive more suitable treatment faster, giving better outcomes. The research was recently published in Scientific Reports. Cancer treatment has undergone […]

New treatment strategy may thwart deadly brain tumors

Immune checkpoint inhibitors are important medications that boost the immune system’s response against certain cancers; however, they tend to be ineffective against glioblastoma, the most deadly primary brain tumor in adults. New research in mice led by investigators at Massachusetts General Hospital (MGH) and the University of Florida reveals a promising strategy that makes glioblastoma susceptible to these medications. The […]

Study: Obesity could affect brain development in children

Published studies have long found a correlation between obesity in children and decreased executive function. New research published in JAMA Pediatrics, based on data mined from a massive national research study, suggests that a change in brain structure—a thinner prefrontal cortex—may help explain that interrelationship. “Our results show an important connection; that kids with higher BMI tend to have a […]
