| external_definition |
Region of brain lying between the midbrain tectum and the thalamus (Sefton and Dreher, in Paxinos, G The rat central nervous system, 1995, pg 859), Situated at the level of poterior commissure and just rostral to the superior colliculus (Brodal, Neurological Anatomy, 3rd ed, 1981, pg 542) A narrow, transversely oriented rostral zone of the mesencephalic tectum, bounded caudally by the superior colliculus, rostrally by the habenular trigone, and laterally by the pulvinar thalami; the pretectal area contains several nuclei that receive fibers from the optic tract; it has bilateral efferent connections with the Edinger-Westphal nucleus of the oculomotor nuclear complex by way of which it mediates the pupillary light refle[MP:0009637]x |
|
| external_ontology_notes |
part of diencephalon in ZFA - modify to adjacent here, supported by pub. Note there is some inconsistency in resources between the region vs nuclei - sometimes they are treated equivalent, sometimes separate (e.g. MP) |
|
| function_notes |
It receives binocular sensory input from retinal ganglion cells of the eyes, and is the region responsible for maintaining the pupillary light reflex |
