Several complexity measures, especially approximate entropy (ApEn) and a new defined complexity measure C ′ 0 , of EEG signals or the ones of the mutual information transmission between different channels of EEGs were calculated to distinguish different consciousness levels for different brain functional states. All of the measures decreased with the following order of brain states: rest with eyes open, eyes closed, light sleep and deep sleep. They decreased during epileptic seizures. On the… CONTINUE READING
