Neurobiology Exam 1 Study Guide

What are the cells which create the retinal cells {Ans: retinal progenitor cells}Decoders {Ans: these turn represent the detect stimulus into neural activity Rods and cones are examples of decoders}Sensory Systems {Ans: these are interconnected circuits that create internal representations of the external and internal world}What type of center surround receptive field does parvocellular neurons have? {Ans: red/green opponent or blue/yellow opponent}Define Ipsolateral/contralateral {Ans: }How could you get bar shaped receptive fields from the simple circular receptive fields in the RGC neurons or layer of v1? {Ans: Essentially, these simple receptive fields project to the LGN, and then these neurons in the LGN synapse on to the same cortical neuron. The overlapping of their receptive fields creates these elongated bar pattern receptive fields}Amacrine cells {Ans: in the inner plexiformlayer, communciate ganglions andbipolar adjacent}What do Starburst Amacrine Cells Do {Ans: Responsible for causing spontaneous waves of activities that sweep across the retina This is because they are connected with cells in a pattern from left to the right To wire up neurons that are in similar spots of visual space that are targets of the RGC The targets are: superior colliculus in the
