High sensitivity of scotopic vision (vision in dim light conditions) is achieved by the rods' low background noise, which is attributed to a much lower thermal activation rate (k<sub>th</sub>) of rhodopsin compared with cone pigments. Frogs and nocturnal geckos uniquely possess atypical rods containing noncanonical cone pigments that exhibit low k<sub>th</sub>, mimicking rhodopsin. Here, we investigated the convergent mechanism underlying the low k<sub>th</sub> of rhodopsins and noncanonical con ...[more]
