Most units receive a total of four projections: one from each of two units on either side. However, unit a receives two, unit h two, unit b three, and unit g three projections. Because they are on or near the edge, these units behave differently. As a result there is an illusion of brightening at the edge as perception differs from luminance. This is an edge effect.

OBS

edge effect: term officially approved by the Electronics and Telecommunications Terminology Committee.
