The photopigment bleaching hypothesis of complementary after-images: a psychophysical test.

چکیده

Normal observers color-adapted simultaneously to two spatially distinct sequencesof light stimulation, equivalent in their bleaching effects but complementary to one anotherin hue. Following the adapting period, observers reported on the color appearance of the twoadjacent after-images seen against a neutral background. The nonequivalence of the two after-images argues against the explanation of complementary a&r-images; based on photo-pigment bleaching; in addition, the fact that the two after-images are mutually complementaryfurther restricts the class of (neural) adaptation hypotheses.

A psychophysical technique for measuring cone photopigment bleaching.

A new, clinically applicable test has been developed to measure the bleaching of the foveal cone photopigments. This noninvasive test is called steady-state color matching. Steady-state color matching is based on the dependence of a color match on the optical density of the cone photopigments. By measuring the color match as a function of retinal illuminance, it is possible to compute the optic...

Photopigment transmittance imaging of the primate photoreceptor mosaic.

We introduce a new technique for classifying many photoreceptors simultaneously in fresh, excised primate retina on the basis of their absorptance spectra. Primate retina is removed from the pigment epithelium and illuminated under a microscope from the same direction as in the intact eye. To facilitate the guiding of light into the receptor outer segments, the optical axes of the photoreceptor...

Slow Cone Reflectance Changes during Bleaching Determined by Adaptive Optics Scanning Laser Ophthalmoscope in Living Human Eyes

To investigate the changes in the reflectance of human cone photoreceptors by an adaptive optics scanning laser ophthalmoscope (AO-SLO) during photobleaching. A custom-built AO-SLO with an observation light of 840-nm was used to measure the cone densities and the reflectance changes during bleaching by 630 nm red light emitting diodes. Measurements were made at 1° and 3° temporal to the fovea w...

Photopigment optical density of the human foveola and a paradoxical senescent increase outside the fovea.

Photopigment optical density (OD) of middle-(M) and long-(L) wavelength-sensitive cones was determined to evaluate the hypothesis that reductions in the amount of photopigment are responsible for age-dependent sensitivity losses of the human cone pathways. Flicker thresholds were measured at the peak and tail of the photoreceptor's absorption spectrum as a function of the intensity of a bleachi...

Cellular mechanisms that underlie bleaching and background adaptation

Experiments were performed on rod photoreceptors isolated from the eye of the larval tiger salamander to determine if the same or different mechanisms underlie the desensitization produced by dim background light (background adaptation) and that which persists in the steady state in darkness after a significant fraction of the photopigment is bleached (bleaching adaptation). We have examined ad...
