- Projection tracts, also known as projection fibers, are a type of white matter tract that connects the cortex with other areas in the CNS, e.g. deep nuclei, brainstem, cerebellum or spine123. They may be efferent (motor) or afferent tracts (sensory)1. The corticospinal tract, for example, carries motor signals from the cerebrum to the spinal cord2. Other projection tracts carry signals upward to the cerebral cortex2.Learn more:✕This summary was generated using AI based on multiple online sources.

The corticospinal tract for example, carries motor signals from the cerebrum to the spinal cord. Other projection tracts carry signals upward to the cerebral cortex.en.wikipedia.org/wiki/Nerve_tractprojection fibers consist of efferent and afferent fibers uniting the cortex with the lower parts of the brain and with the spinal cord. In human neuroanatomy, bundles of axons (nerve fibers) called tracts, within the brain, can be categorized by their function into association fibers, projection fibers, and commissural fibers.en.wikipedia.org/wiki/Projection_fiber
