Corpus Callosum


in placental mammals and man, the aggregation of nerve fibers connecting the cerebral hemispheres.

The corpus callosum develops in the higher mammals from the commissure of the mantle (present in lung-fish, amphibians, reptiles, birds, and cloacal mammals) in connection with the strong development of the cerebral cortex. The fibers of the corpus callosum run mostly in a transverse direction, connecting and exchanging neural impulses between matching areas of the hemispheres. Therefore, both hemispheres together constitute a single unit. Fibers connecting different gyri in the two hemispheres also pass through the corpus callosum (for example, frontal with parietal or occipital). The fibers of the corpus callosum also send collaterals (associative fibers) to different parts of the same hemisphere.

She said: "Music may activate the flow of stored memory material across the corpus collosum so the right and left hemispheres work in harmony, rather than in conflict."
His team finds the frontal cortex and corpus collosum to be especially vulnerable, a result that fits well with Charness' work on L1.
You have no right to a percentage or restriction of the information that flows across my corpus collosum. A) My corpus collosum extends as I see fit, and includes the connection between left brain, right brain, and center brain of myself or of others, as we reserve the right to share thoughts in an idiabatic fashion (for example, closed to you).
