Randomized Controlled Trial
Movement observation-induced modulation of pain perception and motor cortex excitability.
The observation of movements increases primary motor cortex (M1) excitability. This exploratory study examined the effects of movement observation on pressure pain threshold (PPT) and transcranial magnetic stimulation (TMS)-indexed corticospinal excitability bilaterally. ⋯ These exploratory findings support the notion that M1 is a robust modulator of pain-related neural networks. This effect might be mediated through modulation of the GABAergic system and appears to differ from what is observed in chronic pain.

A cortical source localization analysis of resting EEG data after remifentanil infusion.
To explore changes in current source density locations after remifentanil infusion in healthy volunteers using source localization of the electroencephalography (EEG). ⋯ The approach offers the potential to be used for understanding the underlying mechanism of action of remifentanil on brain activity.

Cumulative effects of transcranial direct current stimulation on EEG oscillations and attention/working memory during subacute neurorehabilitation of traumatic brain injury.
To investigate in a randomized, double-blind design, cumulative effects of anodal tDCS on EEG oscillations and neuropsychological tests among patients with traumatic brain injury (TBI) undergoing subacute neurorehabilitation. ⋯ EEG-guided tDCS warrants further investigation as a potential intervention for TBI during subacute neurorehabilitation.

Randomized Controlled Trial
The effects of transcranial direct current stimulation in patients with neuropathic pain from spinal cord injury.
Transcranial direct current stimulation (tDCS) has demonstrated efficacy for reducing neuropathic pain, but the respective mechanisms remain largely unknown. The current study tested the hypothesis that pain reduction with tDCS is associated with an increase in the peak frequency spectrum density in the theta-alpha range. ⋯ The results provide new findings regarding the effects of tDCS on neuropathic pain and brain oscillation changes.

Randomized Controlled Trial
Shutting down sensorimotor interference unblocks the networks for stimulus processing: an SMR neurofeedback training study.
In the present study, we investigated how the electrical activity in the sensorimotor cortex contributes to improved cognitive processing capabilities and how SMR (sensorimotor rhythm, 12-15Hz) neurofeedback training modulates it. Previous evidence indicates that higher levels of SMR activity reduce sensorimotor interference and thereby promote cognitive processing. ⋯ The present findings contribute to a better understanding of the mechanisms underlying SMR neurofeedback training and cognitive processing and implicate that SMR neurofeedback might be an effective cognitive training tool.
