Why are fruits colorful? The relative importance of achromatic and chromatic contrasts for detection by birds
(Springer, 2009-03-01)
The colors of fruits and flowers are traditionally viewed as an adaptation to increase the detectability of plant organs to animal vectors. The detectability of visual signals increases with increasing contrasts between ...

Can red flowers be conspicuous to bees? Bombus dahlbomii and South American temperate forest flowers as a case in point
(2010)
It has been argued that trichromatic bees with photoreceptor spectral sensitivity peaks in the ultraviolet (UV), blue and green areas of the spectrum are blind to long wavelengths (red to humans South American temperate ...
Psychophysical measurements of luminance and chromatic spatial and temporal contrast sensitivity in Duchenne muscular dystrophy
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2011)
In children with Duchenne muscular dystrophy, color vision losses have been related to dystrophin deletions downstream of exon 30, which affect a dystrophin isoform, Dp260, present in the retina. To further evaluate visual ...
Parturition Signaling by Visual Cues in Female Marmosets (Callithrix jacchus)
(Plos One, 2015-06-05)
New World monkeys have polymorphic color vision, in which all males and some females
are dichromats, while most females are trichromats. There is little consensus about which
selective pressures fashioned primate color ...

Importancia de la toma de la campimetría visual computarizada en personas expuestas a solventes orgánicos
(Universidad de La Salle. Facultad de Ciencias de la Salud. Optometría, 2017)
Cone contrast influence on components of the pattern onset/offset VECP
(WILEY-BLACKWELL, 2010)
Transient visual evoked cortical potentials (VECP) were recorded from the scalp of healthy normal trichromats (n = 12). VECPs were elicited by onset/offset presentation of patterned stimuli of two kinds: isochromatic ...
The Appropriateness of Contrast Metric for Reaction Times
(Pion Ltd, 2016-04)
We analyzed different contrast metrics to scale the stimulus strength for suprathreshold reaction times (RTs) when it is modulated along an achromatic channel (L þ M) and both chromatic channels L/M and S/(L þ M) considering ...
