NEUR3112 Study Guide - Final Guide: Occipital Lobe, Visual Cortex, Visual Field
Document Summary
Vision/visual perception -> ability to interpret the surrounding environment using light being focuses on the retina. Processing takes place primarily in the visual cortex (v1)-> in occipital lobe. Accurate representation of the visual field on the retina. Point-to-point representation/mapping of the retina in the primary visual nuclei and primary visual cortex. Appropriate visual experience during "critical periods" of development. Far red spectrum -> maybe beneficial for vision. Low light conditions during critical periods of development-> eyes don"t develop properly -> short sightedness (myopia) Focal point of the eye is in front of the retina. Light can also be damaging and cause retinal degeneration. Anterior structures of the eye -> regulate light entry -> refract light onto retina. Air -> aqueous solution - this is what causes light to relax. Continual adjusting of the pupil size for varying light levels. Feedback between the retina and neurons in the bs -> basic survival and reflex functions.
