Abstract

The electroretinographic response (ERG) of the Drosophila melanogaster eye was recorded in different illumination conditions. A analog/digital conversion system and adequate software was used to process information for quantitative interpretation. The electroretinographic parameters that were comparatively studied, in different light intensities and colors, were the latency time and the adaptation time. It was underlined that the latency time is dependent on the intensity of the white light and on the wavelength of the color light, being longer when the role of the photoreceptors connected to a more distant synapse is stronger.
