TL;DR: The CBP has the potential to provide a substantially more effective BCI than the RCP, especially important for people with severe neuromuscular disabilities.

TL;DR: The historical development and neurophysiological properties of the cVEMP and oVEMP are described and recommendations for recording both reflexes are provided.

TL;DR: This study represents a breakthrough in robotic hand use in amputees and assesses a novel peripheral intraneural multielectrode for multi-movement prosthesis control and for sensory feed-back, while assessing cortical reorganization following the re-acquired stream of data.

TL;DR: This review summarizes the physiological results, the potential artifacts and errors of logic in this area, reconciles apparent disagreements in this field and leads to a new clinical test of utricular function.

TL;DR: Reported technology can reliably perform high-yield decomposition of sEMG signals for isometric contractions up to maximal force levels and should render this technology useful for motor control studies and clinical investigations.

TL;DR: This brief review discusses the methods used to estimate the neural drive to muscles from the surface electromyogram (EMG).

TL;DR: This study shows that the identification of interictal HFOs raises some methodological issues, as the filtering of sharp transients or signals with harmonics can result in "false" ripples, and illustrates complementary methods that can help both researchers and clinicians.

TL;DR: The report by Moliadze and colleagues provides some of the strongest clinical evidence to-date that the relative position of stimulation electrode can affect neuromodulation under each electrode.

TL;DR: Electrode distance plays a critical role in the induction for stimulation after-effects in tDCS and tRNS studies, and must be taken into account in future studies and also when making comparisons with the published literature.

TL;DR: Motivation modulates the P300 amplitude in an ERP-BCI and may contribute to variance inBCI performance and should be monitored in BCI settings.

TL;DR: MSE measures identified an abnormal complexity profile across different temporal scales and their relation to the severity of AD, indicating that entropy-based analytic methods with applied at temporal scales may serve as a complementary approach for characterizing and understanding abnormal cortical dynamics in AD.

TL;DR: Independent on the behavioral condition, epileptic brains exhibited a more regular functional network structure and an increased regularity and a diminished modulation capability appear characteristic of epileptic brain networks.

TL;DR: The present study addressed the use of the infinity reference obtained by the reference electrode standardisation technique (REST) in the study of EEG default mode network (DMN) and showed that REST can exactly recover the true EEG network configuration.

TL;DR: An auditory BCI based on a three-stimulus paradigm that offers communication with binary choices (yes/no) independent of vision may constitute a reliable means of communication for patients who lost all motor function and have a short attention span.

TL;DR: Irrespective of their clinical assessment, a few patients are likely to process sound deviance (MMN) or novelty (nP3), mainly when their state is not due to anoxia, mainly when the aetiology is not related to the time from coma onset.

TL;DR: TRNS has the advantage of higher cutaneous perception thresholds and lower response rates in when compared with tDCS, and this finding points to the application of tRNS as a possible alternative with a better blinding control.

TL;DR: The results suggest that the human M1 shows age-dependent reduction of cortical plasticity, which may be caused by the attenuated responsiveness of intracortical circuits in the M1 and/or disrupted sensorimotor integration within basal ganglia-thalamocortical loop.

TL;DR: Comparison of the power of independent components in depressed patients and healthy controls have revealed significant differences between groups for three frequency bands, which may reflect a decreased cortical activation in these brain regions and a diffuse enhancement of beta power may correlate with anxiety symptoms playing an important role on the onset of depressive disorder.

TL;DR: The experience of phosphenes during tACS involving the visual cortex is influenced by volume conductions effects of the scalp and retinal effects should be taken into account when studying the cortical modulatory effects of tACs.

TL;DR: The present work provides further demonstration of the potential of tACS as a method to selectively modulate the excitability of the visual cortex by demonstrating direct interactions of t ACS with theVisual cortex in a frequency-dependent manner.

TL;DR: An overview of research findings in the last two decades on motion related and contrast sensitivity visual evoked potentials and on auditory event related potentials to basic tone and speech sound processing in dyslexia is provided.

TL;DR: A new, low power EEG recording system with an ultra-high input impedance that enables the use of long-lasting, passive dry electrodes that incorporates Bluetooth wireless connectivity and is designed to be suitable for long-term monitoring during daily activities is presented.

TL;DR: The combination of neuropsychological tests and P300 measurements proved useful in improving reliability and increasing sensitivity to early cognitive decline or disease progression in AD patients.

TL;DR: Recordings of the corticospinal volley evoked by single pulse TMS from the epidural space of conscious patients with chronically implanted spinal electrodes provided insight into the physiological basis of the effects of rTMS and the specific motor cortical circuits involved.

TL;DR: The use of current- controlled DBS may help minimize time-dependent changes in therapeutic efficacy that can complicate patient programming when using voltage-controlled DBS.

TL;DR: The present results support the view that MEP and Rolandic beta oscillation amplitudes are associated with motor cortical excitability, and oscillations seen in EEG reflect the excitability of a large population of cortical neurons, and MEP amplitude is affected also by spinal excitability and action potential desynchronization.

TL;DR: Restoration of normal conduction in demyelinated axons with selective channel blockers improves fatigue and may yet prove useful as a neuroprotective strategy, in preventing secondary axonal degeneration and consequent functional impairment.

TL;DR: Anodal and cathodal tsDCS is a non-invasive and painless method that is able to induce lasting changes in the efficacy of the Ia fibre-motoneurone synapse and might be a valuable new tool in modulating spinal motor pathways.

TL;DR: The findings confirm that the clinical diagnosis of spasticity includes changes in both active and passive muscle properties and the two can hardly be distinguished based on routine clinical examination.
