Assume that cell A of the visual system laterally inhibits the output of the adjacent cell, B. In terms of brightness contrast, what further effect will cell A have on cell B?
A) The more cell A is excited, the more its excitation will spread to cell B
B) The more cell A is excited, the greater the inhibition effect on cell B.
C) The more cell A is excited, the more it will reduce the receptive field of cell B.
D) Cell A's effect on cell B will reverse from an inhibitory effect to an excitatory effect after intense stimulation.

When cell A laterally inhibits the output of adjacent cell B, it means that cell A reduces the output of cell B. Therefore, the more cell A is excited, the greater the inhibition effect on cell B. This is because the lateral inhibition amplifies the differences in brightness between neighboring cells, which means that the output of cell B will be further suppressed by cell A.
