Motor Cortex Stimulation in Parkinson's Disease
Motor Cortex Stimulation (MCS) is less efficacious than Deep Brain Stimulation (DBS) in Parkinson's disease. However, it might be proposed to patients excluded from DBS or unresponsive to DBS. Ten patients with advanced PD underwent unilateral MCS contralaterally to the worst clinical side. A plate electrode was positioned over the motor cortex in the epidural space through single burr hole aft...
متن کاملOn somatotopic representation centers for finger movements in human primary motor cortex and supplementary motor area.
We used functional magnetic resonance imaging to examine the representation pattern for repetitive voluntary finger movements in the primary motor cortex (M1) and the supplementary motor area (SMA) of humans. Healthy right-handed participants performed repetitive individuated flexion-extension movements of digits 1, 2, and 3 using the dominant hand. Contralateral functional labeling for the gro...
متن کاملCommentary on: “Motor Switching and Motor Adaptation Deficits Contribute to Freezing of Gait in Parkinson’s Disease”
More than 50% of Parkinson’s disease (PD) patients exhibit freezing of gait (FoG) characterized by a sudden and transient inability to initiate or continue walking (1). The pathophysiology of FoG is still unknown, particularly due to the difficulty in reproducing this symptom spontaneously in the laboratory, either in humans or in animal models (2, 3). A current hypothesis proposes that FoG cou...
متن کاملGait apraxia after bilateral supplementary motor area lesion.
OBJECTIVES The study aimed at addressing the issue of the precise nature of gait apraxia and the cerebral dysfunction responsible for it. METHODS The case of a patient, affected by a bilateral infarction limited to a portion of the anterior cerebral artery territory is reported. The patient's ability to walk was formally assessed by means of a new standardised test. RESULTS Due to an anomal...
متن کاملComparison of neuronal activity in the supplementary motor area and primary motor cortex.
Neuronal activity in the supplementary motor area (SMA) and primary motor cortex (MI) have been compared in many experiments during performance of many different motor tasks. On one hand, the activity in both areas may appear similar, especially when the motor task is simple. On the other hand, if the motor tasks are more demanding, neuronal activity in the SMA exhibits a variety of complex rel...
