Neurophysiological correlates to the human brain complexity through q-statistical analysis of electroencephalogram.

ABSTRACT: The prospects of assessing neural complexity (NC) by q-statistics of the systemic organization of different types and levels of brain activity were studied. In 70 adult subjects, NC was assessed via the parameter q of q-statistics, applied to the ongoing EEG and of 20 scalp points (channels). The NC were estimated both globally for all channels (AllCh) and locally (for each single channel) in different Functional States (FSs). The values of q was compared among FSs and single channels, as well they were correlated with the power of θ (4-8Hz), [Formula: see text] (15-25Hz) and others EEG bands, in each FS. The value of q across all FSs was higher for AllCh than for the single channels FSs. Consistently with previous studies, we found a negative correlation between NC and age. The FSs did no
