Document Summary
The brain processes stimuli in one region before passing it onto the next. Looking at how our brain processes visual forms. Where" vs. what" pathway: processes specific information and passes it on in the retina and transduce light into a neural impulse: magno: found mainly in periphery of retina (detect changes in brightness / motion. Pioneered a method for recording activity in neurons tried to detect activity in an individual neuron of a squid: this led other researchers to use this technology to see how individual neurons respond to specific stimuli. Al: found that neurons in the optic nerve of a frog respond only to moving black dots these cells = bug detectors". Hubel and wiesel: extended research on neural activity in the visual cortex: mostly with cats and monkeys, earned noble prize. Respond maximally to a bar of certain orientation in a particular region of the retina. Their receptive field are organized in an opponent fashion.
