b)	is not influenced by whether the light falls into the center of the cell’s receptive field or the periphery.

c)	tends to be in one direction (e.g., increased firing) if the stimulation is in the center of the cell’s receptive field and in the opposite direction (e.g., decreased firing) if the stimulation is in the periphery of the receptive field.

d)	is determined either by activation in the center of the cell’s receptive field or by activation in the periphery, but not both.
