This study aimed to investigate reliability of electroencephalography (EEG) during rest and tonic pain. Furthermore, changes in EEG between the two states as well as dynamics and relation to pain ratings were investigated. ⋯ EEG during tonic pain is more pain-specific and should be used in future basic and pharmacological studies.

To determine if vestibular evoked myogenic potential (VEMP) responses change during inversion in patients with superior canal dehiscence syndrome (SCDS) compared to controls. ⋯ VEMP responses are blunted during inversion. Although steady-state measurements of VEMPs during inversion do not increase diagnostic accuracy for SCDS, the findings suggest that inversion may provide more general insights into the equilibration of pressures between intracranial and intralabyrinthine fluids.

Randomized Controlled Trial
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.

Review
Microneurographic recording from unmyelinated nerve fibers in neurological disorders: an update.
Microneurography is a unique neurophysiological technique allowing direct recording of unmyelinated postganglionic sympathetic or afferent nociceptive fibers by tungsten needles inserted into a peripheral nerve fascicle. In recent years, microneurography has been used to ascertain autonomic impairments in central neurological disorders such as sleep disorders, Parkinson's disease, amyotrophic lateral sclerosis, or vasovagal syncope. ⋯ Microneurography has also been used to study nociceptor outflow in pain disorders affecting the peripheral nervous system such as small-fiber neuropathy, diabetic neuropathy, erythromelalgia, complex regional pain syndrome, and fibromyalgia. In these disorders, microneurography mainly documented mechano-insensitive C-nociceptor hyperexcitability that might account for the ongoing pain.

To characterize the risk for seizures over time in relation to EEG findings in hospitalized adults undergoing continuous EEG monitoring (cEEG). ⋯ These findings have implications for patient-specific determination of the required duration of cEEG monitoring in hospitalized patients.
