Triple-cone example Now, moving from the calculations for a single cone to an actual case in which the bottomhole rack was formed by three cones, our considerations are as follows: ...

Having distinct operating ranges requires coordination to cease post-receptor adaptation when receptor adaptation becomes active. The dominance of cone adaptation at high backgrounds cannot be ...

Color vision requires the activity of cone photoreceptors to be compared in post-receptoral circuitry. Decades of psychophysical measurements have quantified the nature of these comparative ...
