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 ...

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 ...

What is the functional relevance of reorganization in primary motor cortex after spinal cord injury?

Neurobiology of Disease, 2019
Motor output maps within primary motor cortex are widely distributed and modified by motor skill learning and neurological injury. Functions that these maps represent after spinal cord injury remain debatable.

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).

Regional glucose hypometabolic spread within the primary motor cortex is associated with amyotrophic lateral sclerosis disease progression: A fluoro-deoxyglucose positron emission tomography study

eNeurologicalSci, 2017
Objective: Here we investigate the process of neurodegeneration in amyotrophic lateral sclerosis (ALS). The relationship between the cortical field spreading of glucose metabolic decreases in the primary motor cortex (PMC) and the progression of ...

Difference between the Effects of Peripheral Sensory Nerve Electrical Stimulation on the Excitability of the Primary Motor Cortex: Examination of the Combinations of Stimulus Frequency and Duration

Brain Sciences, 2022
Peripheral sensory nerve electrical stimulation (PES) excites the primary motor cortex and is expected to improve motor dysfunction post-stroke. However, previous studies have reported a variety of stimulus frequencies and stimulus duration settings, and

Muscle and Movement Representations in the Primary Motor Cortex [PDF]

Science, 1999
What aspects of movement are represented in the primary motor cortex (M1): relatively low-level parameters like muscle force, or more abstract parameters like handpath? To examine this issue, the activity of neurons in M1 was recorded in a monkey trained to perform a task that dissociates three major variables of wrist movement: muscle activity ...

Properties of the primary somatosensory cortex projection to the primary motor cortex in the mouse

Journal of Neurophysiology, 2015
The primary somatosensory (S1) and primary motor (M1) cortices are reciprocally connected, and their interaction has long been hypothesized to contribute to coordinated motor output. Very little is known, however, about the nature and synaptic properties of the S1 input to M1.

Feedforward motor information enhances somatosensory responses and sharpens angular tuning of rat S1 barrel cortex neurons

eLife, 2017
The primary vibrissae motor cortex (vM1) is responsible for generating whisking movements. In parallel, vM1 also sends information directly to the sensory barrel cortex (vS1).
