Optimal parameters for rapid (invisible) frequency tagging using MEG

•This extensive investigation of Rapid Frequency Tagging offers clear suggestions for optimal parameters in order to reliably elicit steady state visual evoked potentials/fields (SSVEP/Fs) that can be recorded using M/EEG while being largely invisible.•We (imperceptibly) flickered patches at various...

Description
Summary:•This extensive investigation of Rapid Frequency Tagging offers clear suggestions for optimal parameters in order to reliably elicit steady state visual evoked potentials/fields (SSVEP/Fs) that can be recorded using M/EEG while being largely invisible.•We (imperceptibly) flickered patches at various locations on a screen in distinct fast frequencies (>60 Hz) and patch sizes of 1 visual degree and larger which can be combined with any visual information on the screen.•Rapid frequency tagging using these optimal parameters allows for examining a range of cognitive phenomena including spatial attention allocation and potentially clinical use or brain computer interfacing. Frequency tagging has been demonstrated to be a useful tool for identifying representational-specific neuronal activity in the auditory and visual domains. However, the slow flicker (
