Comparative Study
A comparative study of cortical responses evoked by transcutaneous electrical vs CO(2) laser stimulation.
A novel non-invasive method for nociceptive electrical stimulation of the skin has been recently introduced by using a planar concentric stimulating electrode (CE). We compared the cortical potentials induced by a CE vs laser stimulator in healthy subjects using a multichannel recording. ⋯ At present, CE-evoked potentials cannot be considered a reliable measure of nociceptive pathway function.

The present study investigated the neural mechanisms of voice pitch control for different levels of harmonic complexity in the auditory feedback. ⋯ This enhancement may enable the audio-vocal system to more effectively detect and correct for vocal errors in the feedback of natural human vocalizations to maintain an intended vocal output for speaking.

Randomized Controlled Trial
Action of 5 Hz repetitive transcranial magnetic stimulation on sensory, motor and autonomic function in human spinal cord injury.
To assess the effectiveness of physiological outcome measures in detecting functional change in the degree of impairment of spinal cord injury (SCI) following repetitive transcranial magnetic stimulation (rTMS) of the sensorimotor cortex. ⋯ Electrophysiological measures may provide a useful adjunct to ASIA impairment scales.

Randomized Controlled Trial
Improving working memory: exploring the effect of transcranial random noise stimulation and transcranial direct current stimulation on the dorsolateral prefrontal cortex.
The aim of this study was to determine if working memory (WM) performance is significantly improved after the delivery of transcranial random noise stimulation (tRNS) to the left dorsolateral prefrontal cortex (DLPFC), compared to an active comparator or sham. ⋯ Anodal tDCS may have significant implications for WM remediation in psychiatric conditions, particularly schizophrenia.

To investigate the presence of multiple spinothalamic pathways for warmth in the human spinal cord. ⋯ Warmth sensation is subserved by parallel spinothalamic pathways, one probably reaching the SII area, the other the ACC.
