Abstract

In the present work we report a new combination of fractal analysis and some advanced statistical methods and their application for the quantitative detection of the effects of a static magnetic field of 2.7 mT on fractal complexity changes of Br neuron activity in the subesophageal ganglia of the garden snail Helix pomatia. We used factor analysis (FA) in the analysis of the empirical distribution of fractal dimension (FD). FA showed that there are two factors in the empirical distribution of FD. Results indicated that the significant changes in the fractal complexity of Br neuron activity occurred during treatment with a magnetic field, were extended to the post exposure period.

Summary

Introduction

Scientific interest in the magnetic field as an ecological and physiological factor and its effect on biological systems has increased over the past decades. Numerous studies (Balaban et al, 1990, McLean et al, 1990; Rosen, 1992, Prato et al, 1996, Ye et al, 2004) have dealt with the effects of magnetic fields on the nervous system. In the present work we report a new combination of fractal analysis and some advanced statistical methods and their use for the quantitative detection of the effects of a static magnetic field of 2.7 mT on the fractal complexity changes of. Previous research (Nikolić et al, 2008) revealed changes in the bioelectrical properties of the Br neuron induced by 2.7 mT and 10 mT static magnetic fields. In this paper, we have applied a different methodology in order to reveal new information about the effect of a 2.7 mT magnetic field on the activity of the Br neuron
