Abstract :
In the first place, we discuss the chaoticity and the Hurst expornent of the alpha rhythms with MEG data under some consciousness states at some positions on the brain. In the second place we present a new preliminary result for the Hurst exponents over extended frequency of rhythms with EEG data under some conditions with/without pleasant visible/auditory stimuli at a frontal position on the brain and discuss on them.
