Abstract

This paper evaluated the correlation among the activations of eyes and brain in visual stimulation. Because of the complex structure of eye fluctuations and brain signals, we employed fractal theory and sample entropy to decode their correlation. Ten subjects looked at four different images with different complexities while we collected their eye fluctuations and EEG signals simultaneously. The results indicated that the variations of the complexity of eye fluctuations and EEG signals are strongly correlated (r = -0.8043 in case of fractal dimension and r = -0.9740 in case of sample entropy), which reflects the correlation among the activations of the eyes and brain. This analysis can be conducted to examine how the activations of other organs are linked to brain activation.
