Sinusoidal flicker characteristics of the color-sensitive mechanisms of the eye
(Elsevier, 1969-05)
The flicker characteristics of the color-receptive systems of the eye were investigated by measuring the modulation thresholds for sinusoidal flicker of one color superimposed on a background of a complimentary color. A ...
The myopic eye of the black moor goldfish
(Elsevier, 1986)
Optical and anatomical methods were used to establish the refractive state of the eye of the Black Moor variety of goldfish. The eye is strongly myopic. The refractive error in 12 eyes from 6 fish ranged from 89 to 268 D.
Square root intensity coding in turtle cones: Physiological mechanisms
(Elsevier, 1990)
The effect of coupling on the intensity-response functions for full field and for slit stimuli was studied by comparing the shapes of the curves obtained from several strongly coupled red cones of turtle with that of one ...
The scotopic threshold response of the cat erg is suppressed selectively by GABA and glycine
(Elsevier, 1991)
Corneal electroretinograms (ERGs) were recorded from anesthetized cats under scotopic conditions. We examined whether the scotopic threshold response (STR) of the ERG could be functionally distinguished from scotopic PII ...
Lateral spread of light adaptation in the rat retina
(Elsevier, 1977)
Recordings from the rat optic tract fibers were used to assess changes in sensitivity under various conditions of adaptation. An adapting background which excites only a small fraction of the rods can yet cause a several-fold ...
Rod saturation in b-wave of the rat electroretinogram under two different anesthetics
(Elsevier, 1984)
B-wave increment threshold experiments in the rat show that "rod saturation" occurs at different background levels with different anesthetics. Rod saturation builds up over the first 60 sec of light adaptation in pentobarbital ...
Mechanisms of light adaptation in rat retina
(Elsevier, 1982)
Green, Dowling, Siegel and Ripps (1975) J. gen. Physiol. 65, 483-502 found that both receptors and post-receptoral elements regulate the process of light adaptation in skate retina. As a test of the generality of this ...
Single retinal ganglion cell responses in the dark-reared rat: Grating acuity, contrast sensitivity, and defocusing
(Elsevier, 1978)
The visual acuity, refractive state, and depth of focus of the dark-reared hooded rat's dark-adapted eye were determined by recording the responses of retinal ganglion cell axons in the optic tract. The smallest square-wave ...
