High-gamma frequency-tagged magnetoencephalography reveals time-resolved task-related functional coupling during spatial cognition (opens in new tab)

Fast periodic visual stimulation (FPVS) combined with magnetoencephalography (MEG) provides a powerful approach for extracting frequency-specific brain responses from perceptual processing areas. However, its application in cognitive paradigms, particularly those addressing visuospatial attention, remains underexplored. This study developed an FPVS-based line bisection paradigm to probe visuospatial cognition during visual exploration of the line center using eye movements without manual resp...
