Alpha coherence predicts accuracy during a visuomotor tracking task.

It has been shown that synchrony of neuronal oscillations plays a critical role in effective communication between functionally distinct brain areas involving motor-sensory integration. However, the patterns of cortico-cortical coupling and their relation to behavioural success are widely unknown. Here, we analysed changes in cortico-cortical coherence during an unimanual visuomotor task and their correlation with performance.

Enhancement of long-range EEG coherence by synchronous bifocal transcranial magnetic stimulation.

Interregional coupling of distant brain regions can be measured by electroencephalographic (EEG) coherence reflecting the spatial-temporal correlation between two oscillatory signals. It has been suggested that this coherence in activity is a signature of functional integration of multimodal neuronal networks. Repetitive transcranial magnetic stimulation (rTMS) is a well-established technique for non-invasive cortical stimulation.
