Emerging Virtual Reality (VR) technologies are gaining momentum, offering innovative tools for applications in fields such as neuroscience. Coupled with advancements in wearable brain measurement techniques such as electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS), these developments enable novel explorations of human brain activation particularly in response to more realistic visual stimuli. We have created a system that integrates EEG and fNIRS within a VR headset, facilitating the monitoring of neuronal activity and cerebral hemodynamics as participants engage in visual tasks. We examined various visual tasks in connection with the brain's induced responses, focusing on potential differences in brain activity when utilizing a 3D VR headset compared to a conventional 2D display. Differences in cerebral responses were examined utilizing time-domain and frequency-domain analysis methods. Observations from the EEG indicated alterations in theta and beta frequency band powers during both stimuli. Furthermore, both oxygenated hemoglobin and deoxygenated hemoglobin showed different responses during the tasks, suggesting alterations in hemodynamic activity. These preliminary findings offer novel methodological insights into the differences in neural and hemodynamic responses between 2D video and VR stimuli.
