• symbolic relative entropy
• average engergy dissipation
• EEG
• time reversal asymmetry

In this letter, we show that the trajectory of electroencephalogram (EEG) possesses the character of time reversal asymmetry, which can provide information about the entropy production of EEG. We develop a kind of new method to estimate symbolic relative entropy and entropy production using forward and backward trajectories. Finally, we use this method to dispose and analyse the EEGs of younger and elder people, and is turned out that this method works and the average energy dissipation can be used as a parameter to detect nonequilibrium.
