The hypothalamospinal tract is a nerve tract that arises mainly from the paraventricular nucleus of hypothalamus, and lateral and posterior areas of the hypothalamus. The tract descends through the periaqueductal gray and adjacent reticular formation.[1] It is found in the dorsolateral quadrant of the lateral funiculus, in the lateral tegmentum of the medulla, pons and midbrain.[2]
The hypothalamospinal tract includes fibres by which the hypothalamus projects to the ciliospinal center in the spinal cord, a part of a brain circuit regulating pupillary dilatation as part of the pupillary reflex.[3]
Lesions of the hypothalamospinal tract cause ipsilateral Horner's syndrome.[2]
