The center-surround arrangement of visual receptive fields  ________________.
|  | 
   |  | involves the relative activity of two concentric circles; | 
   |  | involves a different response to light in the center circle versus the surrounding circle; | 
   |  | results in hyperpolarization in one circle and depolarization in the other when stimulated by light; | 
   |  | increases lateral communication in the retina and therefore the refinement of the signal that reaches visual cortex; | 
   |  | all of the alternatives are correct; | 
   CORRECT - Yes, the center-surround receptive field involves a contrasting response to light in two concentric circles (hyper- or depolarization). This lateral communication increases the resolution of the signal reaching visual cortex.
