EEG Correlation Analysis Under the Condition of +Gz Accelerations
In this research, Electroencephalogram (EEG) data under the condition of +Gz accelerations were recorded and its correlation analysis was done. The correlation change feathers were found for different loads through respective correlation analysis including auto-correlation and cross-correlation analysis for 16 derivation EEG data. The results show that, auto-correlation and cross-correlation are gradually decreased with time lag increasing. Correlation diagrams show that the first peak after zero lags appeared as main peak which responses to relatively stronger correlation. The relationship between correlation and different action of +Gz loads from analysis of a lot of EEG data indicates that EEG correlation is greatly affected by G loads.
