Beta oscillations during spatial working memory performance. Significant decreases in beta (15–20 Hz) activity were observed in the left superior temporal gyrus (top left), right cerebellum (middle central), left inferior parietal lobule, and right intraparietal sulcus (bottom central) throughout the majority of encoding and maintenance (p < 1−8, cluster-corrected). Time courses of beta activity from the peak voxel of each region indicated large decreases immediately following the onset of the encoding grid, which were clearly sustained throughout the remainder of encoding and maintenance.
