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 کاملCaudal Cingulate Infarction Manifesting Astasia
INTRODUCTION Astasia is a rare presenting symptom of stroke, usually known as 'thalamic astasia', induced by a lesion in the ventrolateral thalamus. We report a case of caudal cingulate infarction manifesting astasia. CASE PRESENTATION A 58-year-old male presented with inability to sit, stand and walk (astasia). No apparent motor weakness was noticed in the extremities. MRI revealed cerebral ...
متن کاملSurgical treatment of supplementary motor area lesions.
Different portions of the SMA appear to be engaged by different types of neurological functions. It is important to identify the functional activation of SMA in terms of planning the surgical strategy. Our unpublished data from M.D. Anderson suggest that resection of the site of SMA activation based on fMRI is an important parameter for predicting the postoperative neurological deficit. Also, p...
