In humans, the tectospinal tract (or colliculospinal tract) is a decussating extrapyramidal tract that coordinates head/neck and eye movements.
It arises from the superior colliculus of the mesencephalic (midbrain) tectum, and projects to the cervical and upper thoracic spinal cord levels. It mediates reflex turning of the head and upper trunk in the direction of startling sensory stimuli (visual, auditory, or skin).
