White matter connections of the supplementary motor area in humans

White matter connections of the supplementary motor area in humans.

INTRODUCTION The supplementary motor area (SMA) is frequently involved by brain tumours (particularly WHO grade II gliomas). Surgery in this area can be followed by the 'SMA syndrome', characterised by contralateral akinesia and mutism. Knowledge of the connections of the SMA can provide new insights on the genesis of the SMA syndrome, and a better understanding of the challenges related to ope...

White matter integrity of premotor–motor connections is associated with motor output in chronic stroke patients

Corticocortical functional interactions between the primary motor cortex (M1) and secondary motor areas, such as the dorsal (PMd) and ventral (PMv) premotor cortices and the supplementary motor area (SMA) are relevant for residual motor output after subcortical stroke. We hypothesized that the microstructural integrity of the underlying white matter tracts also plays a role in preserved motor o...

The Role of the Supplementary Motor Area in Inhibitory Control in Monkeys and Humans

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...
