A)   the amount of inhibition right at the intersections is twice as great as the inhibition between each square
B)   the amount of inhibition right at the intersections is much less than the inhibition between each square
C)   the superior colliculus responds maximally as you move your eye from intersection to intersection
D)   moving the eye creates a blur at all the intersections

Neurons in the _____ respond to complex stimuli, but not simple stimuli such as straight lines.

Accepted Answer

A)   LGN
B)   striate cortex
C)   IT cortex
D)   retina
