Ocular Kinematics Measured by In Vitro Stimulation of the Cranial Nerves in the Turtle

Autor: Maria Cano Garcia, James R. Dearworth, Steven C. Nesbit, Chi C. Le

Publikováno v: Journal of Visualized Experiments.

After animals are euthanized, their tissues begin to die. Turtles offer an advantage because of a longer survival time of their tissues, especially when compared to warm-blooded vertebrates. Because of this, in vitro experiments in turtles can be per

Role of the trochlear nerve in eye abduction and frontal vision of the red-eared slider turtle (Trachemys scripta elegans)

Horizontal head rotation evokes significant responses from trochlear motoneurons of turtle that suggests they have a functional role in abduction of the eyes like that in frontal-eyed mammals. The finding is unexpected given that the turtle is genera

A mammalian melanopsin in the retina of a fresh water turtle, the red-eared slider (Trachemys scripta elegans)

Autor: Alison B. Boyd, Laura A. Goldberg, James R. Dearworth, Abraham M. Goch, Ross A. Kalman, Andrew J. Lanzone, Lori J. Cooper, Brian P. Selvarajah

Publikováno v: Vision Research. 51(2):288-295

A mammalian-like melanopsin (Opn4m) has been found in all major vertebrate classes except reptile. Since the pupillary light reflex (PLR) of the fresh water turtle takes between 5 and 10min to achieve maximum constriction, and since photosensitive re

Consensual pupillary light response in the red-eared slider turtle (Trachemys scripta elegans)

Autor: Grayson O. Sipe, James R. Dearworth, Lori J. Cooper, Erin E. Brune, Rhae A.L. Riegel, Angela L. Boyd

Publikováno v: Vision Research. 50(6):598-605

Purpose of this study was to determine if the turtle has a consensual pupillary light response (cPLR), and if so, to compare it to its direct pupillary light response (dPLR). One eye was illuminated with different intensities of light over a four log

Sympathetic influence on the pupillary light response in three red-eared slider turtles (Trachemys scripta elegans)

Autor: Lori J. Cooper, James R. Dearworth

Publikováno v: Veterinary Ophthalmology. 11:306-313

Objective We investigated the effects of phenylephrine and its combination with vecuronium bromide on the iris of turtles to determine if the pupillary light response is affected by sympathetic innervation. Animal studied Three red-eared slider turtl

Parasympathetic control of the pupillary light response in the red-eared slider turtle (Pseudemys scripta elegans)

Autor: C. McGee, James R. Dearworth, Lori J. Cooper

Publikováno v: Veterinary Ophthalmology. 10:106-110

Objective We investigated effects of both vecuronium bromide, a nicotinic cholinergic antagonist, and atropine, a muscarinic cholinergic antagonist, on the pupil of the turtle to determine whether responses to light are controlled by parasympathetic
