A study of power density spectra of split-alpha rhythm
Alpha节律谱分裂现象的研究

EEG (electroencephalogram) power spectra is an important tool studying the functions of brain. Splitting of the alpha spectral peak is a phenomenon observed in a small group of the healthy population. By a simulation study of the corticothalamic model, this paper supposed that the non-uniform time delay was the base of the alpha spectra peak split, and the variety of the cortico-thalamic feedback connection strength was the main reason that the splitting phenomena appeared only in a small group of the population.
