title: [The comparative neurobiology of human and animal color vision].
abstract: Discrimination of colours was studied using instrumental learning paradigm in monkeys (Macaque rhesus) and fishes (Carpio Cyprinus L.). The confusion matrices composed of probabilities of instrumental responses were treated by factor analysis. The spherical structure of perceptual colour space revealed in both animals was close to one in humans. Four eigenvectors constituting four-dimensional Euclidean hyperspheres correspond to red-green, blue-yellow, bright and dark neuronal channels.
