Rapidly flickerig (here 63 and 78 Hz) visual stimuli
presented via a special projector with 1440 Hz refresh rate can be used
for visual frequency tagging.
Importantly, respective steady-state visually evoked responses are
modulated by spatial attention in posterior MEG sensors and can thus
likely be used to track the processing routes of sensory information in
the visual system.
