Résumé :

The ERP of the human eye is studied for violet, blue, green, yellow and red flashes produced with absorption filters. For isoenergetic flashes the amplitude of R1 and of R2 is maximum for the green flash. The R1/R2 ratio however increases progressively from 0 to 1/3 from violet to red flashes. The dark adaptation half time of R2 is 210 sec for violet flashes, suggesting a dominant rod contribution for this color, 90 sec for red flashes, indicating a dominant cone contribution, and 135 sec for green flashes, corresponding to a mixed origin. The dark adaptation half time of R1 is about 100 sec, whatever the wavelength of the flash, which suggests a cone origin for this wave in the human eye.
