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 کاملPoor supplementary motor area activation differentiates auditory verbal hallucination from imagining the hallucination☆
Neuronal underpinnings of auditory verbal hallucination remain poorly understood. One suggested mechanism is brain activation that is similar to verbal imagery but occurs without the proper activation of the neuronal systems that are required to tag the origins of verbal imagery in one's mind. Such neuronal systems involve the supplementary motor area. The supplementary motor area has been asso...
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 Our unpublished data from M.D. Anderson suggest that resection of the site of SMA activation based on fMRI is an important parameter for predicting the postoperative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...
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...
