Document Summary

Visual perception is the most widely studied. Cars that were moving looked like they were standing still (freeze frame) Difficulty following own finger - could only do it if their finger was moving slowly. Associated with activity in the parietal and occipital lobe. Retina - ganglion cells, bipolar cells and photoreceptors. Iris control the amount of light that enters. Fovea centralis - centre of the retina (size of a pin) Neurons communicate information from the retina to the cortex. Photoreceptors excite the bipolar cells, bipolar cells excite the ganglion cells and the optic nerve (optic nerve carries information from the eye to the brain hemispheres) V1 the primary visual projection area or primary visual cortex (located in the occipital lobe. Horizontal cells - connects to multiple rods and even some cones. When stimulated , will inhibit some of the other cells that aren"t being stimulated as much (lateral inhibition)
