lateral corticospinal tract of the medulla

lateral corticospinal tract of the medulla (lcsp)

The term lateral corticospinal tract of the medulla refers to the short portion of fibers descending in the corticospinal tract that separate at the junction of the brain and the spinal cord to form the lateral corticospinal tract ( Carpenter-1983 ).

Also known as: lateral corticospinal tract, Tractus corticospinalis lateralis, Tractus corticospinalis (pyramidalis) lateralis, lateral pyramidal tract, lateral corticospinal tract of the medulla

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
