Course: - somatotopically organized nerve fiber bundle originating in the red nucleus, crossing immediately in the ventral tegmental decussation & descending near the lateral surface of the brainstem & spinal cord just anterior to the corticospinal tract - it terminates in the intermediate zone of the spinal cord Function: - the rubrospinal tract does not appear to have direct connections with spinal motor neurons - impulses carried by the rubrospinal tract indirectly increase flexor motor tone
