Abstract

Strychnine and microwave radiation produced changes in spectral parameters of electrocorticogram, correlation dimension, and Kolmogorov entropy, parameters calculated by the methods of nonlinear dynamics opposite to those induced by urethane. The modulatory effect of microwaves on bioelectric cerebral activity in narcotized animals was similar to the effect of strychnine and probably related to enhanced excitability of brain structures and complication of bioelectric processes.

Main findings

Microwave radiation and strychnine produced changes in electrocorticogram spectral parameters and nonlinear dynamics measures (correlation dimension, Kolmogorov entropy) that were opposite to those induced by urethane. The modulatory effect of microwaves on cerebral bioelectric activity in narcotized rats was described as similar to strychnine and probably related to enhanced excitability and increased complexity of bioelectric processes.
