Nymark S, Frederiksen R, Woodruff M, Cornwall M, Fain G
J Physiol
. 2012 Mar;
590(10):2353-64.
PMID: 22451436
When a substantial fraction of rhodopsin in a rod photoreceptor is exposed to bright light, the rod is desensitized by a process known as bleaching adaptation. Experiments on isolated photoreceptors...

Kolesnikov A, Ala-Laurila P, Shukolyukov S, Crouch R, Wiggert B, Estevez M, et al.
Vision Res
. 2006 Oct;
47(3):363-74.
PMID: 17049961
Photoreceptors of nocturnal geckos are transmuted cones that acquired rod morphological and physiological properties but retained cone-type phototransduction proteins. We have used microspectrophotometry and microfluorometry of solitary isolated green-sensitive photoreceptors...

Kolesnikov A, Shukolyukov S, Cornwall M, Govardovskii V
Vision Res
. 2005 Sep;
46(10):1665-75.
PMID: 16153675
We measured the kinetics of recombination of 11-cis-retinal with opsin in intact frog rod outer segment (ROS). The rhodopsin in ROS was bleached and allowed to decay to "indicator yellow,"...

Ma J, Znoiko S, Othersen K, Ryan J, Das J, Isayama T, et al.
Neuron
. 2001 Nov;
32(3):451-61.
PMID: 11709156
Rods and cones contain closely related but distinct G protein-coupled receptors, opsins, which have diverged to meet the differing requirements of night and day vision. Here, we provide evidence for...

Matthews H, Cornwall M, Crouch R
J Gen Physiol
. 2001 Oct;
118(4):377-90.
PMID: 11585850
During adaptation Ca2+ acts on a step early in phototransduction, which is normally available for only a brief period after excitation. To investigate the identity of this step, we studied...

Kefalov V, Crouch R, Cornwall M
Neuron
. 2001 Apr;
29(3):749-55.
PMID: 11301033
Regeneration of visual pigments of vertebrate rod and cone photoreceptors occurs by the initial noncovalent binding of 11-cis-retinal to opsin, followed by the formation of a covalent bond between the...

Fain G, Matthews H, Cornwall M, Koutalos Y
Physiol Rev
. 2001 Jan;
81(1):117-151.
PMID: 11152756
When light is absorbed within the outer segment of a vertebrate photoreceptor, the conformation of the photopigment rhodopsin is altered to produce an activated photoproduct called metarhodopsin II or Rh(*)....

Corson D, Kefalov V, Cornwall M, Crouch R
J Gen Physiol
. 2000 Aug;
116(2):283-97.
PMID: 10919871
We used 11-cis 13-demethylretinal to examine the physiological consequences of retinal's noncovalent interaction with opsin in intact rod and cone photoreceptors during visual pigment regeneration. 11-Cis 13-demethylretinal is an analog...

. 1999 Feb;
113(2):267-77.
PMID: 9925824
Simultaneous measurements of photocurrent and outer segment Ca2+ were made from isolated salamander cone photoreceptors. While recording the photocurrent from the inner segment, which was drawn into a suction pipette,...
