Asymmetry of parietal interhemispheric connections in humans [PDF]

, 2011
Visuospatial abilities are preferentially mediated by the right hemisphere. Although this asymmetry of function is thought to be due to an unbalanced interaction between cerebral hemispheres, the underlying neurophysiological substrate is still largely ...

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

iNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Responsiveness to exoskeleton loading during bimanual reaching is associated with corticospinal tract integrity in stroke

Frontiers in Neuroscience
BackgroundDevice-based rehabilitation of upper extremity impairment following stroke often employs one-sized-fits-all approaches that do not account for individual differences in patient characteristics.ObjectiveDetermine if corticospinal tract lesion ...

Strategies to augment volitional and reflex function may improve locomotor capacity following incomplete spinal cord injury [PDF]

, 2018
Many studies highlight the remarkable plasticity demonstrated by spinal circuits following an incomplete spinal cord injury (SCI). Such plasticity can contribute to improvements in volitional motor recovery, such as walking function, although similar ...

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Motor function outcomes of pediatric patients with hemiplegic cerebral palsy after rehabilitation treatment: a diffusion tensor imaging study

Neural Regeneration Research, 2015
Previous diffusion tensor imaging (DTI) studies regarding pediatric patients with motor dysfunction have confirmed the correlation between DTI parameters of the injured corticospinal tract and the severity of motor dysfunction.

CSF neurofilament light chain reflects corticospinal tract degeneration in ALS

Annals of Clinical and Translational Neurology, 2015
Diffusion tensor imaging (DTI) is sensitive to white matter tract pathology. A core signature involving the corticospinal tracts (CSTs) has been identified in amyotrophic lateral sclerosis (ALS).

On the notion of motor primitives in humans and robots [PDF]

, 2005
This article reviews two reflexive motor patterns in humans: Primitive reflexes and motor primitives. Both terms coexist in the literature of motor development and motor control, yet they are not synonyms.

The Tumor Suppressor HHEX Inhibits Axon Growth when Prematurely Expressed in Developing Central Nervous System Neurons [PDF]

, 2015
Neurons in the embryonic and peripheral nervoussystem respond to injury by activating transcriptional programs supportive of axon growth, ultimately resulting in functional recovery.

The Spectrum of Abnormal Tongue Movements: Review of Phenomenology, Etiology, and Differential Diagnosis

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Classifying abnormal tongue movements is challenging due to their varied presentations and limited visibility compared to other body parts. Accurate identification of the phenomenology guides physical examination and can point to specific diagnoses.
