Transcranial direct current stimulation (tDCS) on the prefrontal and posterior parietal cortex can enhance mental rotation (MR) performance, whereas little is known about cerebellar tDCS (ctDCS). This study aimed to evaluate effects of ctDCS on a MR task. Fifty-five healthy subjects were randomly assigned to active-ctDCS (1.5 mA; 20 min; n = 28) or sham-ctDCS ( n = 27). Participants performed a MR task before (T0) and after (T...

Emotional processing impairments, resulting in a difficulty to decode emotions from faces especially for negative emotions, are characteristic non-motor features of Parkinson’s disease (PD). There is limited evidence about the specific contribution of the cerebellum to the recognition of emotional contents in facial expressions even though patients with cerebellar dysfunction often lose this ability. In this study, we aimed to...
