Power Spectral Analysis of Different Electroencephalogram Frequency Bands for Epileptic Seizures Induced by Electroconvulsive Therapy in Rats

The quality of epileptic seizures plays a crucial role in evaluating the efficacy of electroconvulsive therapy (ECT). However, due to differences in individual anatomical structures and treatment modes, the electroencephalographic (EEG) signals during epileptic seizures exhibit significant diversity in both the time and frequency domains. This study induced different patterns of epileptic seizures in rats using ECT with different stimulation doses. The power spectral of the δ, θ, α, β, and γ frequency bands of 47 segments of epileptic seizures in 18 rats were calculated to obtain the power spectrum distribution under different patterns of epileptic seizures. This provides an energy perspective for the quality assessment of epileptic seizures. Combined with the time-domain and frequency-domain analysis methods of EEG, it may improve the accuracy of epileptic seizure quality assessment and promote the understanding of the physical and physiological basis of epileptic seizures induced by electroconvulsive therapy.
