corpus callosum









































the corpus callosum (latin for "tough body"), also callosal commissure, is a wide, thick nerve tract consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. the corpus callosum is only found in placental mammals. it spans part of the longitudinal fissure, connecting the left and right cerebral hemispheres, enabling communication between them. it is the largest white matter structure in the human brain, about ten centimetres in length and consisting of 200–300 million axonal projections.

age-related decline in the commissural fiber tracts that make up the corpus callosum indicate the corpus callosum is involved in memory and executive function. specifically, the posterior fibers of the corpus callosum are associated with episodic memory. perceptual processing decline is also related to diminished integrity of occipital fibers of the corpus callosum. evidence suggests that the genu of the corpus callosum does not contribute significantly to any one cognitive domain in the elderly. as fiber tract connectivity in the corpus callosum declines due to aging, compensatory mechanisms are found in other areas of the corpus callosum and frontal lobe. these compensatory mechanisms, increasing connectivity in other parts of the brain, may explain why elderly individuals still display executive function as a decline of connectivity is seen in regions of the corpus callosum.
