Abstract

The biological information extracted from various excitable tissues can be obtained by intracellular as well as by extra-cellular recordings, the latest one being easier and non invasive method with many applications in medicine testing. Electrophysiological recording of the eye excitability is analyzed in the following computational study dedicated to the diagnosis of the type of dynamics governing the compound eye of the superior invertebrates. The Drosophila Melanogaster representing a well consecrated biological model the optoelectronic transduction phenomena inside of its visual system have been investigated by means of the electroretinographic signal recording and analysis. The overlapping of linear and non-linear dynamical trend was evidenced following the application of several computational tests..

Keywords
