Why the study?
Inhibitory control declines with age, but the underlying neural dynamics remain poorly understood, and transient beta-bursts supporting inhibition are often masked by conventional trial-averaged beta-power analyses.
Comparison
Beta-bursting dynamics during response inhibition vs response initiation
Design
Experimental neurophysiological study
Key result
Trial-by-trial analysis of β-bursting during response inhibition revealed distinct spatiotemporal patterns and a functional link to muscle-level suppression absent in averaged β-power data.

Trial-level β-burst analysis may sensitively index motor inhibition; leaves open validation in clinical populations.
Observational (n=20)
β-bursting, analyzed via LMM-TFCE, provides a sensitive, trial-level marker of inhibitory control and cortical suppression of motor output in healthy older adults.
Warden et al. (2025) conducted an observational in Healthy older adults (n=20). Bimanual anticipatory response inhibition task with EEG and EMG was evaluated on Spatiotemporal β-bursting patterns and muscle bursting dynamics. Trial-by-trial analysis of β-bursting during response inhibition revealed distinct spatiotemporal patterns and a functional link to muscle-level suppression absent in averaged β-power data.
