The brain is one of the most complex systems in nature. Brain waves, or the “EEG”, are electrical signals that can be recorded from the brain, either directly or through the scalp. The kind of brain wave recorded depends on the behavior of the animal, and is the visible evidence of the kind of neuronal (brain cell) processing necessary for that behavior. But, EEG had been considered as a virtually infinite-dimensional random signal.
However, nonlinear dynamics light on dynamical aspects of the human EEG. The methods of nonlinear dynamics provide excellent tolls for the study of multi-variable, complex system such as EEG.
In this study, 20 persons separated in 2 groups were examined with EEG, one group stimulated on specific area of the sole of the foot with footbed inside the shoes.
This experiment resulted in at the group stimulated on specific area of the sole of the foot correlation dimension of P4 and O1 channels increased significantly. Therefore, we obserbed that stimulation on specific area of the body had a constant affections on the specific channels.
