White Matter of the Cerebrum
Major White Matter Tracts
White matter in the cerebrum consists of myelinated axons that facilitate communication between brain regions. Major white matter tracts include commissural, association, and projection fibers, each serving distinct functions in neural connectivity.

Understanding White Matter
White matter in the cerebrum consists of myelinated axons responsible for transmitting signals between different regions of the brain.
Major White Matter Tracts
1. Commissural Tracts
These tracts connect the two hemispheres of the brain. The corpus callosum is the largest commissural tract, facilitating interhemispheric communication.
2. Association Tracts
Association fibers connect different regions within the same hemisphere, allowing coordination between various cortical areas.
3. Projection Tracts
Projection fibers connect the cerebral cortex with lower brain regions and the spinal cord, playing a crucial role in motor control and sensory information processing.
Clinical Significance
Damage to white matter can result in neurological disorders such as multiple sclerosis, stroke, and traumatic brain injury, affecting communication between brain regions.
