tracts

In the nervous system, a tract is a bundle of nerve fibers (axons) that run together within the central nervous system (brain and spinal cord). These tracts serve as communication pathways, transmitting signals between different parts of the brain, or between the brain and spinal cord. Think of them as highways for nerve impulses, ensuring that sensory information (like touch or sight) and motor commands (like moving muscles) are efficiently relayed to and from the appropriate areas. Tracts are essential for our ability to perceive, think, and control our movements seamlessly.
