[Analysis of cortical lateralization during mental task of geometric figure rotation].
Mean Kolmogorov entropy within one second is introduced and is used to analyze and localize the cortical lateralization based on spontaneous EEG and nonlinear dynamics. The results of analysis indicate: The conclusion drawn form the use of this method is almost consistent with that from other methods, but this method is more sensitive to cortical lateralization; this method can identify the differences of cortical lateralization between different brain areas. To analyze and localize cortical lateralization, mean Kolmogorov entropy based on spontaneous EEG is a good method.
