The components of complex bioelectrical activity - action potential
(AP), interspike interval (ISI) and the quiet interburst interval (IBI),
along with the effects of 2.7 mT and 10 mT static magnetic fields, were
identified and examined in the spontaneously active Br neuron of the
subesophageal ganglion complex of the garden snail Helix pomatia by
fractal analysis using Higuchi's fractal dimension (FD). The normalized
mean of the empirical FD distributions of bursting activity of the Br
neuron were formed under different experimental conditions: before
(Control), during (MF), and after exposure to the static magnetic field
(AMF). Using the fractal analysis method for the first time, a
separation of the AP, ISI and IBI components was successfully achieved.
Our results show that fractal analysis with deconvolution of the
normalized mean of the empirical FD distributions into Gaussian
functions is a useful tool for revealing the effects of magnetic fields
on the complexity of neuronal bioelectric activity and its AP, ISI and
IBI components.
