Color Controst Perimefry
A method for color perimetry is proposed in which colored test objects are presented in a white surround, so that the luminance of the object and its surround are identical. The color of the testExpand
Single cell spectrally opposed responses: opponent colours or complementary colours?
In the 1950s De Valois and colleagues, followed by other researchers, discovered spectrally opposed single cells in the primate LGN. They called them Red-Green and Yellow-Blue opponent colour cells,Expand
Effects of ageing on postreceptoral short-wavelength gain control: Transient tritanopia increases with age
An unexpected and significant increase of transient tritanopia with age is demonstrated, which cannot be explained by a general decline of short-wave sensitivity or the selective reduction of retinal illumination, and implies that ageing affects also short-wavelength gain control at the site of chromatic opponency or beyond. Expand
The Effect of Age on Dark Focus Distance and Visual Information Transfer Rate
Although the static measure of accommodation is well documented, the dynamic aspect of the resting state (dark focus) of accommodation is still unknown. Previous studies suggest that refractive errorExpand
Analyzing the metrics of the perceptual space in a new multistage physiological colour vision model
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about concrete mechanical properties such as E-modulus and compressive strength. Expand
Beitrag der Rot- und Grünzapfen zum Elektroretinogramm der inneren Netzhaut
Gewidmet allen, die die Hoffnung auf Fertigstellung dieser Arbeit bewahrt haben, als ich schon aufgeben wollte.
1.21 – Blue-ON Cells
The short-wavelength-sensitive cones provide the basis for the blue–yellow color opponent system of human vision. Blue-ON cells receive excitatory input from this cone and inhibitory input from theExpand
Differential effects of D‐amphetamine on red and blue light‐induced photic activation: A novel BOLD fMRI assay of human dopamine function
There was a specific augmentation of the spatial extent of activation to blue, but not red light following D‐amphetamine administration, consistent with the hypothesis that blue light function may have utility as an assay of CNS DA tone. Expand
Human retinal circuitry and physiology
Every second, in an average daytime light environment, hundreds of millions of photons enter the human eye and arrive at the photoreceptor layer of the retina. All our information about the visibleExpand


Enchancement of luminance flicker by color-opponent mechanisms.
Center and surround responses, which are antagonistic at low temporal frequencies, become synergistic at high ones, making these cells most responsive at high frequencies to those wavelengths to which they are least responsive at low frequencies. Expand
Intracellular staining reveals different levels of stratification for on- and off-center ganglion cells in cat retina.
No other morphological feature except stratification appears to be important in determining the sign of the response of these cells, and the nature of the rod and cone pathways to ganglion cells is discussed. Expand
Identification, classification and anatomical segregation of cells with X‐like and Y‐like properties in the lateral geniculate nucleus of old‐world primates.
Two classes of cells are anatomically segregated within the primate lateral geniculate nucleus: X‐like and Y‐like, which receive their excitatory input from retinal cells with slowly conducting axons and these most probably include the tonic ganglion cells described by Gouras. Expand
Concealed colour opponency in ganglion cells of the rhesus monkey retina.
The neutral point of colour‐opponent ganglion cells varies with the geometry and intensity of the stimulus, as well as with the amount of centre‐surround interaction and the receptive‐field location of a cell, so the neutral point is often an ambiguous criterion for identifying colour‐Opponent subtypes on the basis of their cone inputs. Expand
Functional properties of ganglion cells of the rhesus monkey retina.
Three general classes of cells were identified in a sample of 460 cells recorded from all areas of the retina subserving the central 40 degrees of vision in the rhesus monkey, and colour‐opponent, broad‐band and non‐concentric cells were equally represented in all areas. Expand

A model for color vision will be proposed in which six channels (based on the receptive field center mechanism of cells in the midget cell system) excite in various combinations single color sensitive cortical cells. Expand
