摘要：

We have been studying relationship between saccadic eye movements and EEG signals. In precious studies, we confirmed sharply changed EEG signals were recorded just before saccade. The EEG signals in right occipital lobe have low potential in the case of saccade to the right side and the EEG signals in left occipital lobe have low potential in the case of saccade to the left side. However, in the previous study, these EEG signals were analyzed in the time-domain. In this research, we analyze saccade-related EEG signals in the time-frequency domain by wavelet transform. As results,we found two patterns of spectrogram in the case of saccade. In the case of eye movements to the left target, a Pattern-1 appeared in the left hemisphere and the other Pattern-2 appeared in the right hemisphere. By contrast, the Pattern-1 appeared in the right hemisphere and the Pattern-2 appeared in the left hemisphere in the case of eye movements to the right target.
