Document Summary
Sensory transduction: the process by which sensory stimuli are transduced/transferred into slow, graded receptor potentials. Cornea pupil lens retina rods/cones (photoreceptors) Changing the shape of the lens allows the eye to focus on images of near or distant objects onto the retina (accommodation) Each hemisphere receives information from the contralateral half of the visual scene. Optic disc: where the axons conveying visual information gather together and leave the eye through the optic nerve: produces a blind spot because there are no receptors there. Splitting of rhodopsin when exposed to light causes hyperpolarization of the membrane of the photoreceptor. Dorsal lateral geniculate nucleus (lgn): receives input from the retina and projects into the primary visual cortex: optic radiations: projecting axon pathways to the primary visual cortex. Eyes photoreceptor ganglion cell optic nerve optic chiasm lgn or superior colliculus primary visual cortex via optic radiations. Coding of visual information in the retina.
