Visual coding is a highly dynamic process and continuously adapting to the current viewing
context. The perceptual changes that result from adaptation to recently viewed stimuli …

Optogenetic therapies for vision restoration aim to confer intrinsic light sensitivity to retinal
ganglion cells when photoreceptors have degenerated and light sensitivity has been …

The first stage of color vision is now well understood (see Chap. 10). When presented in the
same context under photopic conditions, pairs of lights that produce the same excitations in …

Our ability to see flicker has an upper frequency limit above which flicker is invisible, known
as the “critical flicker frequency”(CFF), that typically grows with light intensity (I). The relation …

Sensory systems constantly adapt their responses to match the current environment. These
adjustments occur at many levels of the system and increasingly appear to calibrate even for …

Arguably, the most important feat of human vision is its ability to operate effectively over the
enormous 10 000-million-fold range of illumination levels to which it can be exposed, from …

Daylight vision starts with signals in three classes of cone photoreceptors sensitive to short
(S), middle (M), and long (L) wavelengths. Psychophysical studies show that perceptual …

Many perceptual dimensions are thought to be represented relative to an average value or
norm. Models of norm-based coding assume that the norm appears psychologically neutral …

Purpose: To assess the intrasession test-retest reliability of scotopic cyan and scotopic red
fundus-controlled perimetry (FCP) in normal subjects using a modified MAIA …

This study investigated changes of short-wavelength fundus autofluorescence (SW-AF) by
retinal bleaching effects. All measurements were performed with the Heidelberg Retina …
