Cells A and B receive the same high levels of stimulation, but cell A shows a lower level of activity relative to cell B. A likely explanation for this fact is that

Lateral inhibition occurs when the activity of one neuron inhibits the activity of neighboring neurons. Therefore, it is possible that cell A is being inhibited by nearby cells, resulting in a lower level of activity compared to cell B. It is unlikely that cell A is defective or has a higher resting level, as both cells are receiving the same high levels of stimulation. The explanation that cell A is receiving input from the edge of a surface also does not make sense in this context, as both cells are receiving the same levels of stimulation regardless of their location on the surface.
