TLDR
Spectral sensitivity determinations showed that this behavior was caused by the green rods, which were not adapted by the red background while other receptor systems were suppressed.About:

Journal ArticleDOI
Utilization of retinoids in the bullfrog retina.
TL;DR: The capacity to generate 11-cis retinal from retinoids arising naturally in the eye was examined in the retina of the bullfrog, Rana catesbeiana, thought to mediate the regeneration of rhodopsin in vivo after extensive bleaching.
Journal ArticleDOI
Light adaptation in the rat retina: evidence for two receptor mechanisms.
TL;DR: Light adapting the rat retina with transient white flashes too dim to bleach a substantial amount of visual pigment produces a change in electroretinogram spectral sensitivity and an increase in flicker fusion frequency.
Journal ArticleDOI
Properties of "neural" adaptation in components of the frog electroretinogram.
TL;DR: Both the b-wave and the PIII component of the electroretinogram of the isolated, perfused frog retina show rapid recovery of sensitivity following exposure to dim adapting lights, and the recovery process appears to be unassociated with visual pigment regeneration.
Journal ArticleDOI
Background adaptation in the rods of the frog's retina.
TL;DR: The experimental results indicate that light‐adaptation decreases q, the number of transmitter molecules released by one bleached rhodopsin molecule, and there is probably an adaptation process also in the rod inner segment, which increases the sensitivty of the rod to transient stimuli.

Light adaptation of the receptors: increment threshold functions for the frog's rods and cones.
Dnald C. Hood,Peggy Ann Hock +1 more
TL;DR: Using sodium aspartate Ringer's, gross potentials from the receptors of the frog's isolated retina are recorded and it is argued that the rods' greater sensitivity to steady background lights is the major cause of their insensitivity in the presence of moderate background lights.

Saturation of the Rod Mechanism of the Retina at High Levels of Stimulation
M. Aguilar,Walter Stiles +1 more
TL;DR: By means of the two-colour threshold method the threshold response of the rod or dark-adapting visual mechanism can be followed to relatively high field intensities and it is concluded that at a field intensity of about 100 scotopic trolands the sensitivity of the rods mechanism to stimulus differences begins to fall off rapidly.

Visual pigments of frog and tadpole (Rana pipiens)
Paul A. Liebman,G. Entine +1 more
TL;DR: The small size and number of cones in frog retinas probably makes the total relative contribution of cone pigment molecules too small for successful spectroscopic studies in extracts.
Journal ArticleDOI
The Site of Visual Adaptation
TL;DR: The b-wave is the first of the known responses in the visual system to show typical adaptation properties, and this suggests that the site of visual adaptation may be in the bi-polarcell layer, the presumed locus of b- wave generation.
