Lateral inhibition is a process by which a group of cells inhibit the activity of their neighbors. This helps in sharpening the contrast between adjacent areas in the visual system. So, if both cells receive the same high levels of stimulation, but one shows a lower level of activity than the other, it is likely that the more active cell is inhibiting the one with lower activity. Hence, the likely explanation for Cell A's lower activity relative to Cell B is that it is being laterally inhibited by other nearby cells.
