An EEG study on the somatotopic organisation of sensorimotor cortex activation during action execution and observation in infancy

Developmental Cognitive Neuroscience, 2015
Previous studies have shown that sensorimotor cortex activation is somatotopically-organised during action execution and observation in adulthood. Here we aimed to investigate the development of this phenomenon in infancy. We elicited arm and leg actions

THE EFFECT OF THE MYOMO ROBOTIC ORTHOSIS ON REACH PERFORMANCE AFTER STROKE [PDF]

, 2013
Stroke affects 795,000 people yearly. Close to 85 percent of stroke survivors experience some degree of stroke-related upper extremity impairment due to spastic paresis (Nakayama, Jorgenson, Pedersen, Raaschou, & Olsen, 1994).

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Effects of Rhythmic Auditory Stimulation During Hemiplegic Arm Reaching in Individuals with Stroke: An Exploratory Study

Hong Kong Journal of Occupational Therapy, 2014
Objective/Background: This study investigated the effects of rhythmic auditory stimulation (RAS) on muscle activity and elbow motion during arm reaching with hemiplegic arm in participants with stroke. Methods: Sixteen adults with stroke who resided in a

Double-Step Paradigm in Microgravity: Preservation of Sensorimotor Flexibility in Altered Gravitational Force Field

Frontiers in Physiology, 2020
The way we can correct our ongoing movements to sudden and unforeseen perturbations is key to our ability to rapidly adjust our behavior to novel environmental demands.

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

Molecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

The re-education of upper limb movement post stroke using iterative learning control mediated by electrical stimulation

, 2009
An inability to perform tasks involving reaching is a common problem following stroke. Evidence supports the use of robotic therapy and electrical stimulation (ES) to reduce upper limb impairments following stroke, but current systems may not encourage ...

Accuracy deficits during robotic time-constrained reaching are related to altered prefrontal cortex activity in children with cerebral palsy

Journal of NeuroEngineering and Rehabilitation
Background The prefrontal cortex (PFC) is an important node for action planning in the frontoparietal reaching network but its role in reaching in children with cerebral palsy (CP) is unexplored.

Human Arm Impedance and EMG in 3D [PDF]

, 2009
This paper shows the relationship between EMG signals and human arm stiffness, measured in 3-D space. Preliminary results demonstrate the viability of this approach, which can then be used to measure human arm impedance from EMG only.
