Document Summary

*context matters a lot when it comes to perception. The eye: lens: focuses light as it enters the eye in a way that hits the retina, retina: contains photoreceptors (rods and cones) which transduce light into electrical signals (action potentials). There"s only one type of rod, 3 types of con receptors. Photoreceptors don"t receive input from other neurons, it receives input from light itself: fovea: the centre of the retina which contains the highest density of cone receptors. Supplies the brain with fine grained details and colour. When we focus on an image, the area in which we"re focusing on has more fine detailing and more colour. Our peripheral vision doesn"t have much colour info or fine detailing. The visual pathway: from the eyes, the visual info travels to the lgn, from the lgn, it passes to a part of the occipital lobe, called the calcarine sulcus.
