Abstract:
Beta oscillations are associated with motor function and are thought to play a role in movement impairment. In a recent magnetoencephalography (MEG) study, Rossiter et al. (J Neurophysiol 112: 2053-2058, 2014) found a disruption in the modulation of movement-related beta oscillations in stroke patients that correlated with motor impairment. We discuss how beta oscillatory measures characterize motor impairment, the implications of stroke variability, and the potential role of GABA in modulating oscillations following stroke and during stroke recovery.
