Document Summary
Lens can perform accommodation (by changing shape to focus on near or far objects) Blind spot (area missing information in our field of vision) Images we see aren"t made of light, but of neural signals. Supercells integrate feature signals to recognize complex forms (like faces) Parallel processing = building perceptions out of sensory details processes in different areas of the brain. Young-helmholtz trichromatic (three-color) theory red, green, blue. Opponent-process theory = neural process of perceiving white as the opposite of perceiving black. Colorblindness cannot differentiate basic colors due to missing cones. Nociceptors = signals interpreted by the brain as pain. Pain circuit = signals that travel to the spinal cord up through nerve fibers, then conduct pain signals to the brain. Gate-control theory = spinal cord contains neurological gate that blocks pain signals or allows them to pass on to the brain. Endorphins = hormones released by the body to reduce pain perception.
