Document Summary
The brain processes stimuli in one region before passing it on to the next. Brain uses division of labour: each region along visual pathway processes speci c info the passes it on. Magno and parvo cells in the retina transduce light into a neuron. Magno and parvo cells in retina: transduce light into neural impulse. Magno cells: found in the periphery of the retina, used for detecting changes in brightness, motion + depth. Parvo cells: found throughout the retina, important for detecting colour, pattern + form. These ganglion cells (with small receptive elds: crucial rst step in object recognition. From retina: axons of these cells leave the eye through the optic nerve, travel to the lgn, end up in primary visual cortex in occipital lobe. Cells in the primary visual cortex: are very particular to what will make them re, called feature detectors. Hodgkin + huxlye pioneered a method for recording activity of neurones.
