Fig. 3From: Distinct cortical activity patterns in Parkinson’s disease and essential tremor during a bimanual tapping taskTapping accuracy. Group results of the tapping accuracy during the 2 and 4 Hz tapping task with and without cue. Statistical differences are marked by an asterisk. HC = Healthy controls; ET = Essential tremor; PD = Parkinson’s disease; C2 = cued tapping task at 2 Hz; NC2 = non-cued tapping task at 2 Hz; C4 = cued tapping task at 4 Hz; NC4 = non-cued tapping task at 4 HzBack to article page
