Shining the light on one eye sends a signal to the brain telling the brain that there is a bright light and the brain responds by sending a signal to constrict both eyes. Click the card to flip 👆.
The horizontal gaze center coordinates signals to the abducens and oculomotor nuclei to reflexively induce slow movement of the eyes. Pathway for fast refixation phase: Afferent signals from the retina are conveyed to the frontal eye field, which sends signals to the superior colliculus, activating the horizontal gaze center in the pons. The ...
8 sie 2023 · Pupillary light reflexes require both optic and oculomotor nerve (cranial nerve III) to constrict pupils upon light exposure. The optic nerve mediates the afferent limb of the pupillary reflex, whereas the oculomotor nerve involves the efferent limb of the reflex.
8 sie 2023 · The visual (retino-thalamocortical) pathway and pupillary light reflex pathway are the two essential ways through which the eye perceives and responds to changes in the environment.
