Assume that Points 1, 2, and 3 are neighboring neural cells on the retina. In which of the following cases would the electrical activity at Point 2 be the GREATEST?
A) a light is shined at Point 1, but not at Point 2 or Point 3
B) a light is shined at Point 2, but not at Point 1 or Point 3
C) a light is shined at Point 1 and Point 2
D) a light is shined at Point 1, Point 2, and Point 3

When a light is shined directly on Point 2, it will create the greatest electrical activity at that point compared to when a light is shined at Point 1 or Point 3. In option A, even though Point 1 is being stimulated, Point 2 is not and therefore will not have the greatest electrical activity. In option C, Point 1 and Point 2 are stimulated, but Point 3 is not, so Point 2 may have increased activity but not necessarily the greatest. In option D, all three points are stimulated, but this does not necessarily mean that Point 2 will have the greatest electrical activity.
