How are tracts named?

Explanation:
Tracts are named for the regions they connect. They’re bundles of axons that carry information from one brain or spinal region to another, so the name shows where they originate and where they terminate. For example, the corticospinal tract starts in the cerebral cortex and ends in the spinal cord, while the spinothalamic tract carries signals from the spinal cord up to the thalamus. This origin-to-destination naming helps you infer the pathway’s route and function. Names aren’t based on how fast they conduct signals, their diameter, or on cranial nerves, which have their own separate naming conventions.
