Modulation of post-movement beta rebound by contraction force and rate of force development (2016)
Journal Article

Movement induced modulation of the beta rhythm is one of the most robust neural oscillatory phenomena in the brain. In the preparation and execution phases of movement, a loss in beta amplitude is observed (movement related beta decrease (MRBD)). Thi...

Spurious correlations in simultaneous EEG-fMRI driven by in-scanner movement (2016)
Journal Article

Simultaneous EEG-fMRI provides an increasingly attractive research tool to investigate cognitive processes with high temporal and spatial resolution. However, artifacts in EEG data introduced by the MR-scanner still remain a major obstacle. This stud... Read More about Spurious correlations in simultaneous EEG-fMRI driven by in-scanner movement.

Global signal modulation of single-trial fMRI response variability: effect on positive vs negative BOLD response relationship (2016)
Journal Article

In functional magnetic resonance imaging (fMRI), the relationship between positive BOLD responses (PBRs) and negative BOLD responses (NBRs) to stimulation is potentially informative about the balance of excitatory and inhibitory brain responses in se...
