Specifically, the tectospinal tract connects the midbrain tectum and the spinal cord.

In humans, the tectospinal tract (also known as colliculospinal tract) is a nerve pathway which coordinates head and eye movements.

The function of the tectospinal tract is to mediate reflex postural movements of the head in response to visual and auditory stimuli.

These are the rubrospinal tract, the vestibulospinal tract, the tectospinal tract and the reticulospinal tract.

It also carries the descending tectospinal tract and medial vestibulospinal tracts into the cervical spinal cord, and innervates some muscles of the neck and upper limbs.
