aNumbers and percentages of beta-neuron pairs with significant task-related and trial-by-trial correlations are presented separately for Monkey T and monkey M low (LO) and high (HI) beta bands. Short and long delay trials are presented separately. Neuronal preferred and nonpreferred movement directions are presented separately for task-related correlations. The proportions of significant correlations with negative sign are specified in separate columns. For the task-related correlation analyses, the numbers of pairs with a significantly stronger correlation coefficient in the original data than in the trial-shuffled resampling control data are specified in separate columns, and their percentages are shown with respect to the total number of analyzed pairs.
