The crossed frontal aslant tract: A possible pathway involved in the recovery of supplementary motor area syndrome
Introduction Supplementary motor area (SMA) syndrome is a constellation of temporary symptoms that may occur following tumors of the frontal lobe. Affected patients develop akinesia and mutism but often recover within weeks to months. With our own case examples and with correlations to fiber tracking validated by gross anatomical dissection as ground truth, we describe a white matter pathway th...
متن کاملInsights from the supplementary motor area syndrome in balancing movement initiation and inhibition
The supplementary motor area (SMA) syndrome is a characteristic neurosurgical syndrome that can occur after unilateral resection of the SMA. Clinical symptoms may vary from none to a global akinesia, predominantly on the contralateral side, with preserved muscle strength and mutism. A remarkable feature is that these symptoms completely resolve within weeks to months, leaving only a disturbance...
متن کاملPost-Operative Supplementary Motor Area Syndrome
Rationale: Surgical removal of the lesions involving the supplementary motor area, results in immediate motor and speech deficits, which in most cases are reversible. Aim: Extent of removal of the supplementary motor area influences the post-operative deficits. Patients and Methods: 12 cases are included in this study, representing lesions involving the supplementary motor area by intra-axial g...
متن کاملA Role for the Frontal Aslant Tract in Speech Planning: A Neurosurgical Case Study.
Frontal and temporal white matter pathways play key roles in language processing, but the specific computations supported by different tracts remain a matter of study. A role in speech planning has been proposed for a recently described pathway, the frontal aslant tract (FAT), which connects the posterior inferior frontal gyrus to the pre-SMA. Here, we use longitudinal functional and structural...
متن کاملRole of the supplementary motor area in motor deficit following medial frontal lobe surgery.
OBJECTIVE Patients undergoing surgical resection of medial frontal lesions may present a transient postoperative deficit that remains largely unpredictable. The authors studied the role of the supplementary motor area (SMA) in the occurrence of this deficit using fMRI. METHODS Twenty-three patients underwent a preoperative fMRI before resection of medial frontal lesions. Tasks included self-p...
