Literature about two illusions that are traditionally linked to lateral inhibitory processes in the retina
is surveyed. Despite much research and a long history, the Mach bands illusion has not yet been
very well-understood. Quantitative data is lacking, while qualitative data is controversial. The Hennann Grid illusion, equally old, has not yet been fully explored either. A critical and a comparative
review of the experiments and the conclusions is carried out, noting common results as
well as contradictory ones. New experiments and a different method of measurement are then
proposed. Some preliminary experiments and their results are included in the appendix together
with a review of recent knowledge about the primate retina and its functioning.
