The video tutorial explains the pupillary light reflex (PLR), involving cranial nerves II (optic) and III (oculomotor). It covers the direct and consensual reflexes, demonstrating how light in one eye affects pupil constriction in the same or opposite eye. The tutorial includes a test demonstration and discusses diagnosing lesions in the reflex pathway, highlighting the effects of lesions on optic and oculomotor nerves.
