(FRAME-INFO (STRING "Tectospinal Tract, Midbrain and Pons Levels. The tectospinal tract originates in the superior colliculus \(tectum\), crosses as a dorsal tegmental decussation and descends contralaterally in the opposite pontine tegmentum somewhat medial to the central tegmental tract, near the midline. The superior colliculus receives somatosensory and auditory input, as well as visual input from both the retina and visual cortex. The function of the tectospinal tract is not well-understood in humans, but it is believed to be involved in the control of orienting movements of the head. "))
