Abstract

The purpose of the experimental and computational investigation was to reveal electromagnetic waves influence in the dynamics of invertebrate visual system. Qualitative and semiquantitative modifications of electroretinographic signal were emphasized. Standard shape of electroretinogram was found significantly changed in most of studied insects. Correlation dimension of visual system attractor as well as the largest Lyapunov exponent have been found statistically affected by electromagnetic exposure. Student t-test was application was able to reveal statistical significant modifications or correlation dimension. Since electromagnetic exposure affected the eye response to high intensity light, phosphoinositide metabolism that is controlling protein kinase C kinetics (responsible for light intensity adaptation), seems to be troubled during electromagnetic treatment.
