Document Summary
Chapter 3 synaesthesia: disorder in which the signals from the various sensory organs are processed in the wrong cortical areas, resulting in the sensory info being interpreted as more than one sensation. Habituation: tendency of the brain to stop attending to constant, unchanging info. Nature of light and how it travels through the various parts of the eye. Iris: its muscles control the size of the pupil. Blind spot: area in retina where the axons of the three layers of retinal cells exit the eye to form the optic nerve, insensitive to light. Axons from temporal halves project to visual cortex on the same side of the brain while axons from the nasal halves cross over to the visual cortex on the opposite side of the brain. Optic chiasm is the point of crossover. Because rods work well in low light, they allow eyes to adapt to low light.
