“…The frequency-stabilising effect is due to phase-lock scalp-recorded alpha rhythm and its influence of the sub-cortical alpha generators within narrow limits set by the inherent EEG frequency [43]. Due to our protocol design, our results could not reveal whether a decreased complexity (relating to increased coherence) of beta waves are the actual result of the alpha resonance-like phenomenon induced by photic stimulation [20].…”

This study has attempted to increase the meaning and significance of findings in the experimental areas of electroencephalographic (EEG) visual or photic driving. The aim of this study was to investigate whether the visual stimulation at particular extremely low frequency order could possibly induce changes in the corresponding EEG frequency bands by examining the functional connectedness between brain regions. This was evaluated by applying the improved experimental protocol and objective using non-parametric spectral estimation coherence algorithm. The findings from our study revealed a significantly higher coherence in the EEG beta2 band (16.6 Hz) corresponding to 16.66 Hz visual stimulation, suggesting a high inter-hemispheric functional connectivity during visual stimulus. A significant increase was revealed during 50 Hz visual stimulation at gamma band and a decrease during 4 Hz visual stimulation at theta band, linked with a substantial transitional shift in predominance from anterior to posterior relative power. This study may also increase the awareness of EEG visual driving response studies in clinical practice to uncover potential neurophysiologic abnormalities.

“…Nonlinearity in largescale brain activity has seen considerable recent interest (Stam, 2005), particularly in healthy resting state activity (Freyer et al, 2009(Freyer et al, , 2011Stam et al, 1999), epileptic seizures (Breakspear et al, 2006;Lehnertz and Elger, 1998;Robinson et al, 2002;Wendling et al, 2000), and functional neuroimaging (Stephan et al, 2008a). Notable nonlinear features in the EEG response to flicker include entrainment and frequency mixing (Herrmann, 2001;Rager and Singer, 1998;Regan, 1989;Townsend et al, 1975), both of which involve interactions between stimuli and ongoing activity and are thus of central importance to understanding brain function (Engel et al, 2001).…”

“…Since the early 1930s, a number of studies have been devoted to the effects of external stimulation on the cortical EEG (Adrian and Matthews, 1934;Walter and Walter, 1949;Townsend et al, 1975;Pigeau and Frame, 1992). Audiovisual stimulation has been reported to influence sleep and learning disorders, neurological disorders, addictions, tension, anxiety, premenstrual syndrome, migraine headaches, etc.…”
