corpus callosum

The first complete mapping of cerebral functional lateralisation has been reported by a Franco-Italian research team. Their results show for the very first time that as well as perception, action and emotions, decision-making uses the right half of the brain more. On the other hand, symbolic communication uses the left half of the brain more… Read more

Neurons’ pattern of firing influence the behavior of the cells that, upon maturation, will provide insulation of neuronal axons, a new study reports. The findings suggest the existence of a complex and nuanced interplay between neurons and the non-neuronal cells that support and protect them. Oligodendrocyte precursor cells (OPCs) give rise to oligodendrocytes, which wrap… Read more

The corpus callosum is a flat bundle of commissural fibers beneath the cerebral cortex in the brains of placental mammals. It spans part of the longitudinal fissure, connects the left and right cerebral hemispheres, and enables communication between the hemispheres. It is the largest white matter structure in the human brain, consisting of 200–250 million… Read more

A new study shows a surprisingly high prevalence of autism is found in patients with a condition known as agenesis of the corpus callosum. This rare disorder is suffered when connections between the left and right sides of their brain are missing. The study, by a team of neuroscientists at Caltech, is the first to show… Read more
