Inter and intra-hemispheric EEG coherence responses to visual stimulations.
This study investigated whether the visual stimulation at extremely low frequency (ELF) could possibly induce changes in the electroencephalographic (EEG) responses. The functional connectedness was examined between the brain regions when the Minimum Variance Distortion-less Response (MVDR) coherence algorithm together with Wilcoxon signed-ranks test statistical method was applied. The results showed that functional significance of EEG alpha rhythms at parietal, and occipital cortex, respond to oscillatory 13 Hz and 16.66 Hz light stimulation, respectively.
