Different modulation of short‐ and long‐latency interhemispheric inhibition from active to resting primary motor cortex during a fine‐motor manipulation task
Performing a complex unimanual motor task markedly increases activation not only in the hemisphere contralateral to the task-performing hand but also in the ipsilateral hemisphere. Transcranial magnetic stimulation studies showed increased motor evoked potential amplitude recorded in resting hand muscles contralateral to the task-performing hand during a unimanual motor task, and transcallosal ...
متن کاملExcitability Change in the Ipsilateral Primary Motor Cortex during a Unilateral Rhythmic Contraction of Finger Muscles : a Neurophysiological Study Using Transcranial Magnetic Stimulation
Recent transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) studies in human demonstrated that while performing a unilateral movement, activity of primary motor cortex (M1) ipsilateral to the movement side contributes to motor performance. been well known that the modulations of ipsilateral M1 (ipsi-M1) excitability are dependent on type of motor task and dif...
متن کاملModulating activity in the motor cortex affects performance for the two hands differently depending upon which hemisphere is stimulated.
We modulated neural excitability in the human motor cortex to investigate behavioral effects for both hands. In a previous study, we showed that decreasing excitability in the dominant motor cortex led to a decline in performance for the contralateral hand and an improvement for the ipsilateral hand; increasing excitability produced the opposite effects. Research suggests that the ipsilateral e...
متن کاملChanges in interhemispheric inhibition from active to resting primary motor cortex during a fine-motor manipulation task.
The effect of performance of a sensorimotor task on the interhemispheric inhibition (IHI) induced from the active primary motor cortex (M1) to the resting M1 was examined in 10 right-handed subjects. Transcranial magnetic stimulation (TMS) was performed to produce motor evoked potentials (MEP) in the resting right (Rt)-first dorsal interosseous (FDI). For the paired-TMS paradigm, a conditioning...
