Simultaneous whole-head electrophysiological recordings using EEG and OPM-MEG (2024)
Journal Article

Electroencephalography (EEG) and magnetoencephalography (MEG) non-invasively measure human brain electrophysiology.

Post‐task responses following working memory and movement are driven by transient spectral bursts with similar characteristics (2024)
Journal Article

The post-movement beta rebound has been studied extensively using magnetoencephalography (MEG) and is reliably modulated by various task parameters as well as illness. Our recent study showed that rebounds, which we generalise as “post-task responses...
