Corticorubral tract
Updates to Article Attributes
Body
was changed:
The corticorubral tract contains neurons that connect the primary motor and sensory areas to the red nucleus. The rubrospinal tract then descends through the spinal cord.
The tract is thought to excite flexor muscles and inhibit extensor muscles.
Gross anatomy
Central connections
The corticorubral tract originates from the primary motor and sensory areas. A majority of the input comes from Brodmann areas 4 and 6.
Course
Corticorubral fibres descend from the cortex and travel through the posterior limb of the internal capsule. The tract terminates on the ipsilateral aspect of the red nucleus. The red nucleus processes data which is then conveyed down the rubrospinal tract.
