Brain Function Lateralisation May Be Distributed Along Four Functional Axes

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. […]

Pattern Of Neuronal Activity Influences Oligodendrocyte Precursor Cells

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 […]

What Is The Corpus Callosum?

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 […]
