Document Summary

Describe the visual system from eye to cortex. Describe how sensory information is translated by our visual system into psychological characteristics. Topic 2: perception of depth and visual objects. Describe the visual cues to that the brain uses to perceive depth. Describe how the visual system detects edges of objects. Describe the cortical processing pathways for visual information. Transparent covering, brings light into eye and acts as lens to focus light. Opening in iris, admits amount of light, changes size to increase or decrease amount of light entering eye. Transparent structure located behind pupil, changes shape with muscles, accommodation: more curved to focus on close items, less curved to focus on far items. Inner surface of back of eye, location of photoreceptors. Neuron in retina that receives information from photoreceptors by means of bipolar cells. Area on retina with densely packed cones, sharpest focus and best colour vision.
