This was not the case. Instead, results suggest that both magno- and parvo-biased information contributes to early, left-lateralized neural processes underlying visual word recognition. (2/2)

Together with recent work by @olaf.dimigen.de on using RIFT with a monitor setup, as well as our own new preprint on using a monitor setup to track attention (www.biorxiv.org/content/10.1...), RIFT is now a lot more accessible both in terms of available recommendations and materials.
Tracking attention using RIFT with a consumer-monitor setup
Rapid Invisible Frequency Tagging (RIFT) is a recent technique that extends the traditional frequency tagging approach by stimulating at frequencies beyond the threshold of perception (≥60Hz). By doin...

Yes, sure, also significant, but wouldn't you agree that lateralization still looks pretty weak (cf. Fig. 8)? But midline periphery (similar to our -12°) is also among weakest signal locations (at least if stimuli not scaled w/ cortical magnif.), so it's probably also a SNR issue in our data.

1) May seem surprising, but very much in line with MEG. See Figs 6 & 8 in Minarik et al., 2023, NeuroImage who mapped 15 VF locations.
2) The pilot described here was run with DC-EOG, but without ET; that's part of an ongoing follow-up

Our small pilot study shows RIFT works with an affordable 480 Hz OLED monitor & EEG:
✅ Reliable timing
✅ Robust tagging at 60 & 64 Hz to barely visible flicker
✅ Even weak peripheral responses
We hope this opens the door to RIFT studies by more labs.

Hi Martin, the preprint refers to "Supporting Information" that seems to be not in the document. Is the full version available somewhere?
