6/ Strikingly, lateralised mu/beta modulation was weaker in PWS than TFS. This difference coincided with the time of between-action shifts, a period of high uncertainty regarding which action to select and when. 📉

4/ We used lateralised sensorimotor mu/beta-frequency (8–30 Hz) activity as a proxy of the relative prioritisation of one hand action among competing options. 🧠

3/ To explore this, we recorded MEG from 20 people who stutter (PWS) and 20 typically fluent speakers (TFS) during a visuomotor working-memory task requiring temporally structured selection, preparation, and shifts between left- and right-hand actions. ✋

The B&C Lab is excited to attend the @vssmtg.bsky.social. William, @sabomelinda.bsky.social, and @irenetxeberria.bsky.social will each present posters. Lab alumni @danielagresch.bsky.social and @jamalamal.bsky.social will also present projects conducted in collaboration with the B&C Lab. #VSS2026

⏱️ Strikingly, this difference was specific to periods of uncertainty about which action was required and when - precisely when temporal structuring demands were greatest - and disappeared once action identity and timing became predictable. n/n

👐 We found that lateralised sensorimotor mu/beta (8-30 Hz) activity modulation related to hand action prioritisation differed between the groups. 4/n

🧠 To address this question, we recorded magnetoencephalography (MEG) in a group of people who stutter and a group of typically fluent speakers while they performed a visuomotor working-memory task which encourages dynamic selection and shifts between hand actions. 3/n
