Projection fibers of the brain
Projection fibers of the brain, also known as projection tracts of the brain are a type of white matter tract that connects the cortex with other areas in the CNS, e.g. deep nuclei, brainstem, cerebellum or spine. They may be efferent (motor) or afferent tracts (sensory).
Projection fibers that can be identified by fiber tracking include
- corticospinal tract (CST)
- corticopontine tracts
- corticobulbar tract (CBT)
- medial lemniscus (tracts in the brainstem)
- optic radiation (or geniculocalcarine tract)
