Positive and Negative Potential Responses associated with Vertebrate Photoreceptor Cells

Nature, 1965
IN a previous paper it was shown, by means of an electrophoretic staining technique, that negative d.c. potentials, similar to the S potentials of fish retinae, can be recorded from, the inner segments of photoreceptor cells during retinal illumination1. These responses were referred to as photoreceptor potentials.

The Traffic of Particles in the Axonic Process of Vertebrate Cone-Type Photoreceptor Cells

Zoological Science, 1995
Differential-interference-contrast microscopy with video enhancement displayed the movement of particles for the first time in the isolated axonic process of cone-type photoreceptor cells of Rana catesbiana. This movement was observed under visible light which visual pigments could absorb.

Molecular mechanisms underlying selective synapse formation of vertebrate retinal photoreceptor cells

Cellular and Molecular Life Sciences, 2019
In vertebrate central nervous systems (CNSs), highly diverse neurons are selectively connected via synapses, which are essential for building an intricate neural network. The vertebrate retina is part of the CNS and is comprised of a distinct laminar organization, which serves as a good model system to study developmental synapse formation mechanisms ...

Molecular mechanisms of vertebrate retina development: Implications for ganglion cell and photoreceptor patterning

Brain Research, 2008
Although the neural retina appears as a relatively uniform tissue when viewed from its surface, it is in fact highly patterned along its anterior-posterior and dorso-ventral axes. The question of how and when such patterns arise has been the subject of intensive investigations over several decades.

PHOTORECEPTOR CELL TYPES IN THE RETINA OF VARIOUS VERTEBRATE SPECIES: IMMUNOCYTOCHEMISTRY WITH ANTIBODIES AGAINST RHODOPSIN AND IODOPSIN

Photochemistry and Photobiology, 1992
Abstract— Types of photoreceptor cells in the retinas of 36 species of vertebrates (5 classes, 14 orders) were investigated immunocytochemically with monoclonal antibodies against chicken iodopsin (Io‐mAb) and antiserum against bovine rhodopsin (Rh‐As).

Model feedback mechanism between horizontal cells and photoreceptors of the vertebrate retina

Neurophysiology, 1977
A model with nonlinearity of the photoreceptor presynaptic membrane as its important distinguishing feature was created on the basis of the hypothesis that feedback between the horizontal cells and photoreceptors is effected by a current generated by the subsynaptic membrane of the horizontal cells and leaking partly into the photoreceptors ...

Centrins, A Novel Group Of Cat2,2+-Binding Proteins In Vertebrate Photoreceptor Cells

2002
Changes in the intracellular Ca2+-concentration affect the visual signal transduction cascade directly or more often indirectly through Ca2+-binding proteins. Here we review recent findings on centrins in photoreceptor cells of the mammalian retina. Centrins are members of a highly conserved subgroup of the EF-hand super-family of Ca2tbinding proteins ...

A Photon Counting Microspectrophotometer for the Study of Single Vertebrate Photoreceptor Cells

1978
In order to have a satisfactory description of how the visual system works, particularly a description on which one can base adequate quantitative as well as qualitative theories of visual function, including both normal and abnormal color perception, it’s obviously necessary to understand how photoreceptor cells transduce light signals.

Involvement of cGMP and calcium in the photoresponse in vertebrate photoreceptor cells.

The Journal of the Florida Medical Association, 1995
The biochemical and physiological events responsible for reaction of the rod photoreceptor cells in the vertebrate eye have provided insight into the mechanisms involved in signal transduction in other cells. The light-mediated changes in the photopigment, rhodopsin, in the photoreceptive region of these photoreceptors initiates a cascade of events ...
