It has been possible to use viral-mediated gene therapy to transform dichromatic (red-green
color-blind) primates to trichromatic. Even though the third cone type was added after the …

Some primate populations include both trichromatic and dichromatic (red–green colour
blind) individuals due to allelic variation at the X-linked opsin locus. This polymorphic …

Purpose.: Inherent instability of the P23H mutant opsin accounts for approximately 10% of
autosomal dominant retinitis pigmentosa cases. Our purpose was to develop an overall set …

The color vision of most platyrrhine primates is determined by alleles at the polymorphic X‐
linked locus coding for the opsin responsible for the middle‐to long‐wavelength (M/L) cone …

The present study evaluated the efficacy of an adapted version of the Mollon-Reffin test for
the behavioral investigation of color vision in capuchin monkeys. Ten tufted capuchin …

In the Jastrow size illusion, two vertically stacked but offset stimuli of identical size are
misperceived such that the bottom stimulus is overestimated relative to the top stimulus due …

Cytochrome oxidase histochemistry reveals large‐scale cortical modules in area V2 of
primates known as thick, thin, and interstripes. Anatomical, electrophysiological, and tracing …

The pitheciines (Chiropotes, Pithecia, and Cacajao) are frugivorous Neotropical primates
that specialize on the predation of seeds from unripe fruits, usually cryptic against the …

To have color vision, having at least two cone photopigment types with different spectral
sensitivities present in distinct photoreceptors is necessary together with the neural circuitry …

Vision is a major sense for Primates and the ability to perceive colors has great importance
for the species ecology and behavior. Visual processing begins with the activation of the …
