Motor demand dependent activation of ipsilateral motor cortex 1
28 29 The role of ipsilateral primary motor cortex (M1) in hand motor control during complex 30 task performance remains controversial. Bilateral M1 activation is inconsistently 31 observed in fMRI studies of unilateral hand performance. Two factors limit the 32 interpretation of these data. As the motor tasks differ qualitatively in these studies, it is 33 conceivable that M1 contributions dif...

The role of ipsilateral primary motor cortex (M1) in hand motor control during complex task performance remains controversial. Bilateral M1 activation is inconsistently observed in functional (f)MRI studies of unilateral hand performance. Two factors limit the interpretation of these data. As the motor tasks differ qualitatively in these studies, it is conceivable that M1 contributions differ w...
متن کاملSuppression of ipsilateral motor cortex facilitates motor skill learning.
The primary motor cortex (M1) plays a critical role in early aspects of motor skill learning. Given the notion of inter-hemispheric competition, unilateral disruption of M1 may increase excitability of the unaffected motor cortex and thus improve motor learning with the ipsilateral hand. We applied slow-frequency repetitive transcranial magnetic stimulation (rTMS) before the initiation of pract...
متن کاملMotor demand-dependent improvement in accuracy following low-frequency transcranial magnetic stimulation of left motor cortex.
The role of primary motor cortex (M1) in the control of voluntary movements is still unclear. In brain functional imaging studies of unilateral hand performance, bilateral M1 activation is inconsistently observed, and disruptions of M1 using repetitive transcranial magnetic stimulation (rTMS) lead to variable results in the hand motor performance. As the motor tasks differed qualitatively in th...
متن کاملThe Ipsilateral Human Motor Cortex Can Functionally Compensate for Acute Contralateral Motor Cortex Dysfunction
What promotes motor recovery from stroke? To date, studies of recovery from stroke have shown alterations in function in various cortical areas, including the contralesional (unaffected) motor cortex (M1). However, whether these changes contribute to recovery or are mere epiphenomena remains unclear. We therefore sought evidence that the ipsilateral M1 can compensate for dysfunction of the cont...
