  • Title: [The chromatic characteristics of neuronal receptor fields in the visual cortex of the baronduki].
    Author: Polkoshnikov EV, Chetyrbok IS.
    Journal: Neirofiziologiia; 1988; 20(2):262-5. PubMed ID: 3398977.
    Abstract:
    39 orientation-selective neurons and 25 neurons responding to total illumination of the receptive field were investigated by exposing to achromatic and chromatic stimuli. Switching on and off of the bar stationary stimuli has revealed that orientation-selective neurons were not chromatically opponent. But when they were tested by moving chromatic bars, pronounced maximum responses were found either to green (520-540 nm) or to blue (449-458 nm) colours. 7 neurons of 39 were either not activated by exposure to achromatic stimuli of any brightness or were slightly activated. Among 25 neurons responding to total illumination of receptive field, 5 neurons were chromatically opponent. They responded by prolonged tonic activation to the switching on of the green and switching off of the blue stimuli.
