Noninvasive vagus nerve stimulation alters neural response and physiological autonomic tone to noxious thermal challenge. [PDF]

, 2019
The mechanisms by which noninvasive vagal nerve stimulation (nVNS) affect central and peripheral neural circuits that subserve pain and autonomic physiology are not clear, and thus remain an area of intense investigation.

Optogenetic stimulation of the motor cortex alleviates neuropathic pain in rats of infraorbital nerve injury with/without CGRP knock-down

The Journal of Headache and Pain, 2020
Background Previous studies have reported that electrical stimulation of the motor cortex is effective in reducing trigeminal neuropathic pain; however, the effects of optical motor cortex stimulation remain unclear.

Quantitative GABA magnetic resonance spectroscopy as a measure of motor learning function in the motor cortex after subarachnoid hemorrhage

Frontiers in Neurology, 2023
The neural mechanisms underlying gross and fine motor dysfunction after subarachnoid hemorrhage (SAH) remain unknown. The γ-aminobutyric acid (GABA) deficit hypothesis proposes that reduced neuronal GABA concentrations and the subsequent lack of GABA ...

Altered Modulation of Silent Period in Tongue Motor Cortex of Persistent Developmental Stuttering in Relation to Stuttering Severity [PDF]

, 2016
Motor balance in developmental stuttering (DS) was investigated with Transcranial Magnetic Stimulation (TMS), with the aim to define novel neural markers of persistent DS in adulthood. Eleven DS adult males were evaluated with TMS on tongue primary motor

Quantitative patterns of motor cortex proteinopathy across ALS genotypes

Acta Neuropathologica Communications, 2020
Degeneration of the primary motor cortex is a defining feature of amyotrophic lateral sclerosis (ALS), which is associated with the accumulation of microscopic protein aggregates in neurons and glia. However, little is known about the quantitative burden

The Neural Basis of Age-Related Changes in Motor Imagery of Gait: An fMRI Study [PDF]

, 2017
Background. Aging is often associated with modifications of gait. Recent studies have revealed a strong relationship between gait and executive functions in healthy and pathological aging.

All Talk and No Action: A Transcranial Magnetic Stimulation Study of Motor Cortex Activation During Action Word Production [PDF]

, 2011
A number of researchers have proposed that the premotor and motor areas are critical for the representation of words that refer to actions, but not objects. Recent evidence against this hypothesis indicates that the left premotor cortex is more sensitive

Electroacupuncture-Induced Plasticity between Different Representations in Human Motor Cortex

Neural Plasticity, 2020
Somatosensory stimulation can effectively induce plasticity in the motor cortex representation of the stimulated body part. Specific interactions have been reported between different representations within the primary motor cortex.

BDNF val66met polymorphism is associated with modified experience-dependent plasticity in human motor cortex. [PDF]

, 2006
Motor training can induce profound physiological plasticity within primary motor cortex, including changes in corticospinal output and motor map topography.

Low-frequency cortical activity is a neuromodulatory target that tracks recovery after stroke. [PDF]

, 2018
Recent work has highlighted the importance of transient low-frequency oscillatory (LFO; <4 Hz) activity in the healthy primary motor cortex during skilled upper-limb tasks.
