Decoding motor imagery EEG from the same limb

Link – Decoding multiclass motor imagery EEG from the same upper limb by combining Riemannian geometry features and partial least squares regression. Abstract OBJECTIVE: Due to low spatial resolution and poor signal-to-noise ratio of electroencephalogram (EEG), high accuracy classifications still suffer from lots of obstacles in the context of motor imagery (MI)-based brain-machine interface (BMI) […]

Challenging the use of left-temporal EEG alphawaves

Link – All talk? Challenging the use of left-temporal EEG alpha oscillations as valid measures of verbal processing and conscious motor control. Abstract This study tested the validity of EEG left-temporal alpha power and upper-alpha T7-Fz connectivity as indices of verbal activity and conscious motor control. Participants (n = 20) reached for, and transported, a jar under […]

Exoskeleton walking increases cortical activation

Link – Passive, yet not inactive: robotic exoskeleton walking increases cortical activation dependent on task. Abstract BACKGROUND: Experimental designs using surrogate gait-like movements, such as in functional magnetic resonance imaging (MRI), cannot fully capture the cortical activation associated with overground gait. Overground gait in a robotic exoskeleton may be an ideal tool to generate controlled […]

Ergogenic Effects of Bihemispheric tDCS on Fitness:

Link – Ergogenic Effects of Bihemispheric Transcranial Direct Current Stimulation on Fitness: a Randomized Cross-over Trial. Abstract Several types of routines and methods have been experimented to gain neuromuscular advantages, in terms of exercise performance, in athletes and fitness enthusiasts. The aim of the present study was to evaluate the impact of biemispheric transcranial direct […]

tDCS on dichotic listening.

Link – A multimodal study of the effects of tDCS on dorsolateral prefrontal and temporo-parietal areas during dichotic listening. Abstract The underlying neural mechanisms of transcranial direct current stimulation (tDCS), especially beyond the primary motor cortex, remain unclear. Several studies examined tDCS effects on either functional activity, neurotransmitters, or behavior but few investigated those aspects […]

Cortical Activation During Shoulder and Finger Movements

Link – Cortical Activation During Shoulder and Finger Movements in Healthy Adults: A Functional Near-Infrared Spectroscopy (fNIRS) Study. Abstract Characterization of cortical activation patterns during movement of the upper extremity in healthy adults is helpful in understanding recovery mechanisms following neurological disorders. This study explores cortical activation patterns associated with movements of the shoulder and […]

Posttraining tACS Impairs Motor Consolidation

Link – Posttraining Alpha Transcranial Alternating Current Stimulation Impairs Motor Consolidation in Elderly People. Abstract The retention of a new sequential motor skill relies on repeated practice and subsequent consolidation in the absence of active skill practice. While the early phase of skill acquisition remains relatively unaffected in older adults, posttraining consolidation appears to be […]

Effects of 2mA & 4mA tDCS on Muscle Activity

Link – Different Effects of 2 mA and 4 mA Transcranial Direct Current Stimulation on Muscle Activity and Torque in a Maximal Isokinetic Fatigue Task. Abstract Studies investigating the effects of transcranial direct current stimulation (tDCS) on fatigue and muscle activity have elicited measurable improvements using stimulation intensities ≤2 mA and submaximal effort tasks. The […]

Electrophysiological Effects of tDCS in Rats

nathan whitmore and his rats

Link – Electrophysiological Effects of Transcranial Direct Current Stimulation on Neural Activity in the Rat Motor Cortex. Abstract Transcranial direct current stimulation (tDCS) is a non-invasive technique that modulates the neuronal membrane potential. We have previously documented a sustainable increase in extracellular dopamine levels in the rat striatum of cathodal tDCS, suggesting that cathodal tDCS […]

Bihemispheric tDCS for upper-limb hemiparesis

Link – Bihemispheric tDCS for upper-limb hemiparesis in acute stroke: a randomized, double-blind, sham-controlled trial. Abstract BACKGROUND AND PURPOSE: Neuromodulation is a promising approach to increase motor recovery in stroke. However, so far, there is a scarcity of evidence documenting the clinical potential of tDCS administered in the acute phase of stroke. The present study […]
