Abstract: The complex phenomena that occur at cellular and molecular level within the visual cells are still partially understood. The model organism Drosophila melanogaster represents a very suitable investigation tool for the researchers’ effort to elucidate the behavior of human visual system since its well known genetic plasticity offers the possibility of diverse new mutants yielding for comparative study. Although it is an apparently simple living being, D. melanogaster is provided with an extremely well developed visual system – as most of dipteran insects represented by it. Many of the information obtained by studying D. melanogaster could be extrapolated for the human visual system – even its visual neuron are in smaller number and have limited functions. The study of the eye electric activity recorded by non-invasive methods (electroretinogram) is the objective of the present work where some hypotheses related to the molecular reactions occurring in the photoreceptor cells are discussed based on experimentally captured visual signal.
