And here the poster!

If you are at #CNS2025, check out this brilliant poster #F98 from @edwardody.bsky.social @straubeb.bsky.social where we probed for action-specific "quasi-predictive" effect independent of probability-based expectations!

🧵4) We then did temporal generalization. Here, broadband EEG did not show pattern similarity between both time windows. But the neural pattern was similar when we looked at the alpha amplitude. By-subject correlation also suggests positive correlation between both windows in the alpha band.

🧵3) We then decoded task modality. In motor preparation, active showed higher decoding accuracy than passive, suggesting enhance prediction. But in the perception time window, decoding accuracy was lower in the active condition, suggesting less difference between modalities (again suppression).

🧵2) We looked at the EEG around the bimodal stimuli. Univariate ERP shows that RP differed between movements and task modalities, but did not show any interaction (A-B). Sensory VEP suggests a clear active suppression: the modality difference was reduced in the active movement.

🧵1) Participants made active (self-initiated) or passive (finger moved by electromagnet) movements triggering bimodal auditory/visual stimuli. They were followed, in a block-wise manner, by unimodal auditory/visual comparison stimuli, and participants judged which stimulus was brighter or louder.

🧵4) We then used temporal generalisation to see if neural pattern between preparation and perception windows are similar. While broadband EEG didn't show it (4AB), the pattern of the alpha amplitude is shared between both windows (4CD). Also, by-subject correlation suggests high correlation (4E)

🧵3) We decode task modality. Based on the broadband EEG, we saw higher decoding of active movement during motor preparation, but lower accuracy during sensory perception (3A). Motor preparation difference is likely driven by the slow wave (3C), and sensory difference primarily phase-locked (3H)

🧵2) Univariate ERP shows sensitivity of the readiness potential to both movements and task modality (but no interaction), Figure 2A-C, and sensory visual ERP already shows an active suppression effect for modality attention difference (Figure 2D-F)
