Answer to Question 1

Answer: A

Answer to Question 2

Answer: Cells in the striate cortex integrate information from a variety of visual cells in such a
way that a cell may respond to visual stimuli that are more complicated than those of ganglion cells in the retina. An annular receptive field for each of a set of ganglion cells may report to a cell in the striate cortex in such a way that a bar of light that stimulates the center of each ganglion cell receptive field causes the striate cell to fire. Stimuli that do not precisely stimulate the center fields of an array of ganglion cells would not stimulate the striate cortex cell. Different features (line, arc, circle) could be built up from different converging patterns to the striate
cortex.
