Dark continuous noise from visual pigment as a major mechanism underlying rod–cone difference in light sensitivity

Proceedings of the National Academy of Sciences, Volume 121, Issue 51, December 2024.
SignificanceRetinal rods exhibit two kinds of dark spontaneous phototransduction activity. One is quantal noise originating from thermal isomerization of rhodopsin. The other is continuous noise believed for almost three decades to come from intrinsic …
