PSYCH 10 Lecture Notes - Lecture 6: Color Constancy, Subjective Constancy, Sensorineural Hearing Loss
Document Summary
Within the electromagnetic spectrum, our eyes can only see the visible spectrum (400 - 700 nm) The eye: light passes through the cornea and the pupil, and is focused and inverted by the lens. The lens can perform accommodation by changing shape to focus on near/far objects: light then lands on the retina, where it begins the process of transduction into neural impulses to be sent out through the optic nerve. Photoreceptors in the retina convert the information into neural impulses, which travel through the optic nerve and into the brain where this information is processed. Retina: light triggers photochemical reaction in rods and cones at the back of the retina, chemical reaction activates bipolar cells, bipolar cells activate ganglion cells, the axons of which converge to form the optic nerve. This nerve transmits information to the visual cortex (via the thalamus) in the brain.
