Optic tracts definition chemistry
WebThe majority of nerve fibers in the optic tract connect to the LGN. Several nerve fibers leave the optic tract before the LGN to connect to sub cortical structures through out the brain. These parts of the brain regulate things like: eye and head movements, pupillary light reflex - (pupil size), and circadian rhythms - (light/dark cycle). WebThe optic chiasm extends from the ventral surface of the caudal part of the preoptic area to the hypothalamus at the level of the caudal border of the suprachiasmatic nucleus (Watson and Paxinos, 2010).The optic chiasm lies immediately ventral to the suprachiasmatic nucleus and the third ventricle. The optic tract moves laterally and caudally to wrap …
