Definition

Periventricular white matter refers to white matter located immediately adjacent to the fluid-filled ventricles of the brain.

Current Knowledge

Periventricular white matter is composed of bundles of myelinated nerve fibers (axons). These bundles appear “white” due to the heavy myelination of these fast-conducting fiber tracts, which convey motor and sensory information to their targets within the spinal cord and cerebrum, respectively. Periventricular white matter tracts are adjacent to the cerebrospinal fluid (CSF) filled cavities of the brain: the two lateral, single third, and single fourth ventricles.

Nomenclature

Periventricular white matter within the cortex is named according to the lobe of the brain in which it is located: frontal, parietal, temporal, or occipital; for example, the periventricular white matter within the frontal lobe is referred to as frontal periventricular white matter and surrounds the anterior horn of the lateral ventricle. The parietal...
