[edit] lateral inhibition- explanation

Our brain see the image as a collection of vertical lines (because the gradient is horizontal). Every stripe has a value but the brain calculates the contrast of a stripe oppose to its neighbour stripes. That's why the stripes in edges of the gradient looks as if they are brighter or darker than their real value, they have less inhibition than the stripes in the uniform area.
