EEG features during maintaining a human body balance.

We have conducted an experiment involving keeping balance on a platform to research the perception of maintaining body posture. The objective of the present work was to characterize the common features of cortical activity during postural control. Regarding the cortical basis of performance differences during unstable conditions, EEG analysis suggest that central-frontal areas may underlie the cortical interaction including oscillations in general, maybe underlie cortical monitoring of changes in postural state of the body. The obtained results show that the neuronal activity in the β-frequency band can be utilized as the neurophysiological marker of the subject’s ability to maintain the equilibrium state.
