It is well-established that during goal-directed motor tasks, patients with essential tremor have increased oscillations in the 0\u20133 and 3\u20138 Hz bands. It remains unclear if these increased oscillations relate to activity in specific brain regions. This study used task-based functional magnetic resonance imaging to compare the brain activity associated with oscillations in grip force output between patients with essential tremor, patients with Parkinson\u2019s disease who had clinically evident tremor, and healthy controls. The findings demonstrate that patients with essential tremor have increased brain activity in the motor cortex and supplementary motor area compared with controls, and this activity correlated positively with 3\u20138 Hz force oscillations. Brain activity in cerebellar lobules I\u2013V was reduced in essential tremor compared with controls and correlated negatively with 0\u20133 Hz force oscillations.<\/p>\n

Widespread differences in brain activity were observed between essential tremor and Parkinson\u2019s disease. Using functional connectivity analyses during the task evidenced reduced cerebellar-cortical functional connectivity in patients with essential tremor compared with controls and Parkinson\u2019s disease. This study provides new evidencethat in essential tremor 3\u20138 Hz force oscillations relate to hyperactivity in motor cortex, 0\u20133 Hz force oscillations relate to the hypoactivity in the cerebellum, and cerebellar-cortical functional connectivity is impaired.<\/p>\n
