Which structure connects the two cerebral hemispheres?

The major structure that links the two cerebral hemispheres is a thick bundle of myelinated nerve fibers that spans the midline. This white matter tract serves as the primary communication bridge between the left and right sides, enabling coordinated movement, sensation, and higher functions by sharing information across hemispheres. It sits beneath the outer cortex and connects corresponding areas across hemispheres. Understanding the other terms helps: the cerebrum refers to the entire brain with its two hemispheres; grey matter is the outer cortex made of neuron cell bodies; white matter consists of the axon tracts that carry signals, including the corpus callosum. Among these, the corpus callosum is the specific structure that directly connects both hemispheres.
