TL;DR: These guidelines provide an up-date of previous IFCN report on “Non-invasive electrical and magnetic stimulation of the brain, spinal cord and roots: basic principles and procedures for routine clinical application” and include some recent extensions and developments.

TL;DR: This up-dated review will highlight important knowledge and recent advances in the contribution of pharmaco-TMS-EMG and pharmacological characterization of the TMS-evoked EEG potentials to understanding of normal and dysfunctional excitability, connectivity and plasticity of the human brain.

TL;DR: An overview of methodological considerations throughout the analysis pipeline of recording and analyzing resting state EEG and MEG data, with a focus on functional connectivity and network analysis and how methodological choices in resting state research can affect the construction of functional networks.

TL;DR: Induced sensations are modulated by electrode size and intensity and mainly pertain to the cutaneous receptor activity of the somatosensory system.

TL;DR: Applying machine learning methods on a reduced subset of proposed features could predict seizure onsets with high performance, and is of very low computational cost, while providing acceptable levels of alarm sensitivity and specificity.

TL;DR: Results of this study show that pattern recognition and graph of brain network, on the basis of the resting state fMRI data, can efficiently assist in the diagnosis of Alzheimer's disease.

TL;DR: It is shown for the first time that intra- individual variability is lower than inter-individual variability, and with fair intra-individual inter-sessional reliability for 30 min after AtDCS-subjects are likely to maintain their response patterns to tDCS between sessions, with implications for experimental and therapeutic applications of tDCS.

TL;DR: Gain-related delta activity may provide unique information about reward dysfunction in major depression and other internalizing psychopathology, and may be a composite of loss- and gain-related neural activity, reflecting distinct facets of reward processing.

TL;DR: The findings in the present study suggest that cortical hyperexcitability occurs upstream to a seemingly intact lower motor neuronal system in sporadic amyotrophic lateral sclerosis, suggesting a cortical origin of the disease.

TL;DR: The differences in target ERP components between people with ALS and age-matched HVs are consistent with the growing recognition that ALS may affect cortical function and the development of BCIs for use by this population may begin with studies in HVs but also needs to include studies inPeople with ALS.

TL;DR: It is demonstrated for the first time that disrupted cortical hubs existed in patients with SAD during resting state, and may provide novel insight into understanding of pathophysiological mechanisms underlying SAD.

TL;DR: The results demonstrate the feasibility of detecting the intention of gait initiation from EEG signals, on a single trial basis and are important for the development of new gait rehabilitation strategies, either for recovery/replacement of function or for neuromodulation.

TL;DR: The ACNS EEG terminology can be used to identify highly malignant EEG-patterns in post cardiac arrest patients in an international context with high reliability and will increase the usefulness of routine EEG to assess neurological prognosis after cardiac arrest.

TL;DR: This study demonstrates that substantial risk stratification is possible based on early EEG abnormalities, and has implications for patient-specific determination of the required duration of cEEG monitoring in hospitalized patients.

TL;DR: Results and insights gained from the growing body of research focused on epilepsy from a network perspective are reviewed, putting an emphasis on two different notions of network connectivity: functional and effective; and studies investigating these notions in epilepsy are highlighted.

TL;DR: The source localization is improved when electrode numbers increase, but the absolute improvement in accuracy decreases with increasing electrode number, which can more ably assist the physician to better plan for surgical procedures.

TL;DR: It is suggested that 10 anodal tDCS sessions may beneficially modulate regulation of cortical excitability for patients with TBI and warrants further investigation as a potential intervention for TBI during subacute neurorehabilitation.

TL;DR: In this paper, the effects of two daily tDCS sessions over a 5-day period in treatment-resistant depression were investigated, and the tDCS was well tolerated, with mild adverse events limited to transient scalp discomfort.

TL;DR: Results suggest that N170/VPP abnormalities index non-specific facial affect processing dysfunction in these neurological and psychiatric conditions, reflecting social impairments being broadly characteristic of these groups.

TL;DR: The automatic seizure detection method EpiScan showed high sensitivity and low false alarm rate in a prospective multi-center study on a large number of patients and will raise the efficiency of video-EEG monitoring and the safety levels of patients.

TL;DR: For the first time, the study demonstrates age-specific influences of tDCS on cortical excitability of the primary motor cortex, and the stimulation protocols of the tDCS have to be optimized according to age by planning studies in pediatric population.

TL;DR: The findings are consistent with the possibility that anodal tDCS over the left M1 may be effective, at least in part, because it results in an increase in M1 cortical excitability, perhaps due to a pain inhibitory effect of motor cortex stimulation that may influence the descending pain modulation system.

TL;DR: Combined EEG and high resolution EEG can provide distinct multi-scale estimates of functional connectivity in both healthy and diseased brains with measures like frequency and phase spectra, covariance, and coherence.

TL;DR: The proposed work studied abnormally increased connectivity of brain functional networks in patients with depression by combing the clustering coefficient and the characteristic path length and found that the brain networks of patients with Depression and healthy controls had regular networks during emotion processing.

TL;DR: Age-related declines in otolith function are confirmed, and a protective effect of black race on oVEMP latency and amplitude is observed, and the odds of absent responses were significantly higher in individuals age⩾80 for oVEMPs, and age ⩾70 for cV EMPs.

TL;DR: Results indicate that SMR neurofeedback improves stimulus processing capabilities and consequently leads to improvements in cognitive performance, and contribute to a better understanding of the mechanisms underlying SMR Neurofeedback training and cognitive processing.

TL;DR: The present results show that based on accumulated dataset it is possible to distinguish HFO features different for SOZ and non-SOZ channels, and to show changes in HFO characteristics during the transition from interictal to preictal and to ictal periods.

TL;DR: UPSS and its sub-scores operationalize to diagnose acute and subacute-onset CIDP and its variants with high sensitivity, specificity, and PPV and gives a new diagnostic power to the method of the peripheral nerve ultrasound.

TL;DR: The results showed that the sensitivity and specificity of MUS in diagnosing ALS was almost equivalent to those of EMG, using the Awaji criteria.

TL;DR: AC 500Hz stimulation was slightly better than BC 500 Hz in demonstrating abnormalities in patients with VN, and is as effective as BC 500Hz for investigating VN.
