Subthalamic deep brain stimulation in Parkinson׳s disease has no significant effect on perceptual timing in the hundreds of milliseconds range

Paired difference in performance thresholds according to DBS status. The first and third measures within each triplet show performance for that run with DBS 'on' compared to that with DBS 'off'; values greater than zero denote poorer performance with DBS 'on', while those less than zero denote poorer performance with DBS 'off'. The middle measure shows the difference in performance between the two runs with DBS 'on'. Error bars denote confidence intervals.110
