Description[edit | edit source]
The Rubrospinal tract is a descending pathway which originates in the Red Nucleus and descends to the spinal cord.[1]
Anatomy[edit | edit source]
Origin[edit | edit source]
- The Red Nucleus of the midbrain tegmentum [1]
Course / Path[edit | edit source]
- Fibres pass ventromedially and cross the ventral tegmental decussation.
- Fibres descend to the spinal cord where they lie ventrolateral to and intertwined with the corticospinal tract.
Function[edit | edit source]
- As the Rubrospinal tract recieves afferent fibres from the motor cortex and cerebellum it acts as a non pyramidal route of influencing spinal cord activity through inter and motor neurones [1][2]
- Neural activity in the red nucleus is related to force, velocity and direction of movement. [3]
