Dynamic Increase in Corticomuscular Coherence during Bilateral, Cyclical Ankle Movements [PDF]

, 2017
In humans, the midline primary motor cortex is active during walking. However, the exact role of such cortical participation is unknown. To delineate the role of the primary motor cortex in walking, we examined whether the primary motor cortex would ...

Visual feedback alters force control and functional activity in the visuomotor network after stroke. [PDF]

, 2018
Modulating visual feedback may be a viable option to improve motor function after stroke, but the neurophysiological basis for this improvement is not clear.

Partially Overlapping Sensorimotor Networks Underlie Speech Praxis and Verbal Short-Term Memory: Evidence from Apraxia of Speech Following Acute Stroke

Frontiers in Human Neuroscience, 2014
We tested the hypothesis that motor planning and programming of speech articulation and verbal short-term memory (vSTM) depend on partially overlapping networks of neural regions. We evaluated this proposal by testing 76 individuals with acute ischemic

Changes in excitability and GABAergic neuronal activity of the primary somatosensory cortex after motor learning

Frontiers in Neuroscience, 2022
IntroductionIt is widely known that motor learning changes the excitability of the primary motor cortex. More recently, it has been shown that the primary somatosensory cortex (S1) also plays an important role in motor learning, but the details have not ...

Attention-dependent modulation of neural activity in primary sensorimotor cortex [PDF]

, 2013
Although motor tasks at most times do not require much attention, there are findings that attention can alter neuronal activity not only in higher motor areas but also within the primary sensorimotor cortex.

Neuronal Plasticity and Age-Related Functional Decline in the Motor Cortex

Cells, 2023
Physiological aging causes a decline of motor function due to impairment of motor cortex function, losses of motor neurons and neuromuscular junctions, sarcopenia, and frailty.

Local Differences in Cortical Excitability – A Systematic Mapping Study of the TMS-Evoked N100 Component

Frontiers in Neuroscience, 2021
Transcranial magnetic stimulation (TMS) with simultaneous electroencephalography applied to the primary motor cortex provides two parameters for cortical excitability: motor evoked potentials (MEPs) and TMS-evoked potentials (TEPs).

Spontaneous activity patterns in human motor cortex replay evoked activity patterns for hand movements

Scientific Reports, 2022
Spontaneous brain activity, measured with resting state fMRI (R-fMRI), is correlated among regions that are co-activated by behavioral tasks. It is unclear, however, whether spatial patterns of spontaneous activity within a cortical region correspond to ...

Motor recovery following capsular stroke [PDF]

, 1993
The functional anatomy of motor recovery was studied by assessing motor function quantitatively in 23 patients following capsular or striatocapsular stroke.

Analysis of Time-Dependent Brain Network on Active and MI Tasks for Chronic Stroke Patients.

PLoS ONE, 2015
Several researchers have analyzed brain activities by investigating brain networks. However, there is a lack of the research on the temporal characteristics of the brain network during a stroke by EEG and the comparative studies between motor execution ...
