N2 - In this paper, the brain activity was studied and observed while person was in the loss of balance state due to vestibular system disorder. Brain activity was recorded as QEEG data which was analyzed by the Z-scored FFT method. The experimental results showed brain activities in the positions O1, O2, P3, P4, PZ, T5, and T6 in the forms of topographic map (Absolute Power) and brain connectivity (Amplitude Asymmetry). It was represented in the topographic map that, during the loss of balance state, brain areas at occipital and parietal lobes have high intensity level of brain processing. For brain connectivity, the results clearly showed the brain connections while subjects were trying to maintain their balances. These strong connections were represented by red lines between O1, O2 positions (occipital lobe) and P z (parietal lobe), Fz (frontal lobe) and Cz (central lobe). Similarly, there were strong connections between T5 and Fz positions and T5 and T6 positions. On the other hand, the connection between T6 and Fz was found to be a weak connection. The analysis of results can be employed in the alarm system of pilot during aerobatics.
