… As we make saccades to explore a visual scene, retinal neurons encounter a wide range
of light intensities. Receptor and post-receptor adaptation permit the amplification required to …

… adaptation processes are, in order of processing of the light input: a divisive light adaptation,
a subtractive light adaptation… Divisive light adaptation is modeled by two gain controls. The …
