Pain-motor integration in the primary motor cortex in Parkinson's disease [PDF]

Brain Stimulation, 2017
In Parkinson's disease (PD), the influence of chronic pain on motor features has never been investigated. We have recently designed a technique that combines nociceptive system activation by laser stimuli and primary motor cortex (M1) activation through ...

Enhanced Primary Motor Cortex Astrocyte Calcium Signaling With Motor Learning [PDF]

Neural Plasticity
Astrocytes form an integral part of the nervous system and are proposed to modulate neuronal circuits and behavior. The motor cortex plays a key role in the planning and execution of voluntary movements and makes key contributions to motor skill learning.

Inconsistent primary motor cortex glucose hypometabolism in primary lateral sclerosis. [PDF]

J Neurol
Abstract Objective Primary lateral sclerosis (PLS) is a rare neurodegenerative disorder and a model for upper motor neuron degeneration, which is believed to begin in the primary motor cortex. However, clinical observation suggests that not all PLS cases show primary motor cortex glucose hypometabolism on 2-deoxy-2 ...

Betz cells of the primary motor cortex. [PDF]

J Comp Neurol
Abstract Betz cells, named in honor of Volodymyr Betz (1834–1894), who described them as “giant pyramids” in the primary motor cortex of primates and other mammalian species, are layer V extratelencephalic projection (ETP) neurons that directly innervate α‐motoneurons of the brainstem and spinal cord.

Apraxia and motor dysfunction in corticobasal syndrome [PDF]

, 2014
Background: Corticobasal syndrome (CBS) is characterized by multifaceted motor system dysfunction and cognitive disturbance; distinctive clinical features include limb apraxia and visuospatial dysfunction. Transcranial magnetic stimulation (TMS) has been

Optogenetic Neuronal Stimulation Promotes Functional Recovery After Spinal Cord Injury

Frontiers in Neuroscience, 2021
Although spinal cord injury (SCI) is the main cause of disability worldwide, there is still no definite and effective treatment method for this condition.

Illusory sensation of movement induced by repetitive transcranial magnetic stimulation. [PDF]

PLoS ONE, 2010
Human movement sense relies on both somatosensory feedback and on knowledge of the motor commands used to produce the movement. We have induced a movement illusion using repetitive transcranial magnetic stimulation over primary motor cortex and dorsal ...

A longitudinal study of hand motor recovery after sub-acute stroke: a study combined FMRI with diffusion tensor imaging. [PDF]

PLoS ONE, 2013
Previous studies have shown that motor recovery of stroke can be assessed by the cortical activity and the structural integrity of the corticospinal tract (CST), but little is known about the relation between the cortical activity and the structural ...

Task-free functional MRI in cervical dystonia reveals multi-network changes that partially normalize with botulinum toxin. [PDF]

PLoS ONE, 2013
Cervical dystonia is characterized by involuntary, abnormal movements and postures of the head and neck. Current views on its pathophysiology, such as faulty sensorimotor integration and impaired motor planning, are largely based on studies of focal hand

Aberrant brain oscillatory coupling from the primary motor cortex in children with autism spectrum disorders

NeuroImage: Clinical, 2021
Autism spectrum disorder (ASD) often involves dysfunction in general motor control and motor coordination, in addition to core symptoms. However, the neural mechanisms underlying motor dysfunction in ASD are poorly understood. To elucidate this issue, we
