Abstract

There are presented the computational simulations of the optoelectronic effects in the biophysical processes involved by light absorption and the transmission of the membrane generated potential from the receptor cells to the neurons. The physical system is the compound eye of Drosophila Melanogaster flies. The experimental electroretinograms recorded at various frequencies between 8 and 60 Hz are well modelled by a system of two nonlinear, coupled oscillators. The understanding of the mechanisms of optoelectronic biological processes is a current topic of great scientific interest because of its potential applications..
