Document Summary
Processes stimuli in one region before passing it on to the next. Magno and parvo cells in the retina transduce light into a neural impulse. Pioneered a method for recording activity in neurons. Neurons in optic nerve of a fro respond only to moving black dots. Responds maximally to a bar of a certain orientation in a particular region of the retina. The receptive field of simple cells is organized in an opponent fashion. Responds maximally to a bar of a certain orientation and direction of movement, regardless of where the bar is located within the receptive field. Complex cells are indifferent to the position of light on its receptive field. Responds maximally to a bar of a particular orientation and direction of movement, ending at specific points within the receptive field. H(cid:455)per(cid:272)o(cid:373)ple(cid:454) (cid:272)ells re(cid:272)eptive fields have a regio(cid:374) of i(cid:374)hi(cid:271)itio(cid:374) at the e(cid:374)d. Must be combined to make sense of a visual scene.
