Detrended fluctuation analysis (DFA) was applied to the heartbeat fluctuation of spiny lobster, Panulirus japonicus. The analysis revealed the difference of the scaling exponent between two conditions of heart : (1) the heart of the living lobster which was under restrained condition, and (2) the heart was isolated from the lobster. The exponent was 0.8 for the condition (1), which means the fluctuation has long-range correlation like 1/f fluctuation. On the other hand, the exponent of (2) was 0.5, which is in good agreement with the value for white noise. The result suggests that the long-range correlation of the heartbeat fluctuation comes from the brain-CNS control.
