Document Summary
Class 2, lecture 3, chapter 2: the neural basis for cognition. The primary motor area of the brain is adjacent to the primary sensory area of the brain. Vision is the modality through which much of our knowledge is acquired. Vision provides an excellent illustration for how the close study of the brain can proceed, and what it can teach us. Two types of photoreceptors, or cells that respond to light, are found on the retina: rods. Lower acuity low detail detection, very grainy, not very fine. Found in periphery of the retina: cones. Higher acuity able to perceive detail, much more densely packed. A series of neurons communicates information from the retina to the cortex: in the eye. Ganglion cells and the optic nerve (which has direct connection to the visual cortex): in the thalamus. Lateral geniculate nucleus (lgn: in the cortex. V1, the primary visual projection area, or primary visual cortex, located in the occipital lobe.
