Functional heterogeneity of the supplementary motor area.
BACKGROUND AND PURPOSE The purpose of this study was to assess supplementary motor area (SMA) activation during motor, sensory, word generation, listening comprehension, and working memory tasks by using functional MR imaging (fMRI). Human supplementary motor area (SMA) has been shown to play roles in motor control and other various functions such as sensory, speech expression, and memory. Howe...
متن کاملFunctional Localization of the Supplementary Motor Area
The supplementary motor area (SMA) is a key structure involved in behavioral planning and execution. Although many reports have indicated that SMA is organized somatotopically, its exact organization remains still unclear. This study aimed to functionally map SMA using functional magnetic resonance imaging (fMRI) and validate the fMRI-SMA by electrocortical stimulation (ECS) and postsurgical sy...
متن کاملRestored activation of primary motor area from motor reorganization and improved motor function after brain tumor resection.
BACKGROUND AND PURPOSE Reorganization of brain function may result in preservation of motor function in patients with brain tumors. The goal of the present study was to investigate whether function of the primary motor area (M1) was restored and whether motor function improved after brain tumor resection. METHODS Five patients with metastatic brain tumors located within or near M1 underwent a...
متن کاملBilateral supplementary motor area syndrome causing akinetic mutism following parasagittal meningioma resection
The supplementary motor area (SMA-proper) is important for the programming and execution of motor, speech, and other elaborative functions. Unilateral SMA syndrome is well described. We present two patients who underwent resection of a large parasagittal meningioma in proximity to the SMA-proper in both hemispheres. Following surgery, these patients developed akinetic mutism; the maximal clinic...
متن کاملElectrophysiological and functional connectivity of the human supplementary motor area
Neuro-imaging methods for detecting functional and structural inter-regional connectivity are in a rapid phase of development. While reports of regional connectivity patterns based on individual methods are becoming common, studies comparing the results of two or more connectivity-mapping methods remain rare. In this study, we applied transcranial magnetic stimulation during PET imaging (TMS/PE...
