Document Summary
Magno and parvo cells: magno and parvo cells in the retina transduce the light stimulus into a neural impulse. Magno cells are found mainly in the periphery of the retina, are used for detecting changes in brightness, motion, and depth. Parvo cells are found throughout the retina, and important for detecting colour, pattern and form. Ganglion cell, with their small receptive elds > crucial rst step to object recognition. From the retina, axons of these cells exit the eye via the optic nerve, to the lgn, and end up in the primary visual cortex in the occipital lobe. Feature detectors > cells that are very particular about what will make them re. 1952, recorded the electrical activity in an individual neuron of the squid. Paved the way for other researchers to use this technology to see how individual neurons respond to speci c stimuli.
