The present study evaluated ethnic differences in sensory, pain responses, and the exteroceptive suppression reflex (ES) in the trigeminal region. ⋯ The findings of this study have direct implications for studies evaluating different types of orofacial pain conditions and trigeminal reflexes.

Controlled Clinical Trial
Laser evoked potentials in carpal tunnel syndrome.
The aim of this study was to evaluate the function of Adelta fibers at the hand level in patients with clinical symptoms of Carpal Tunnel Syndrome (CTS) using CO(2) laser evoked potentials (LEPs), in light of the intensity and distribution of sensory symptoms and pain. ⋯ The finding of reduced sensory symptoms in patients with severe thin afferents damage, may suggest a slight expression of central sensitisation phenomena in the advanced stage of CTS syndrome.

To establish a methodology for recording corticobulbar motor evoked potentials (CoMEPs) from vocal muscles after transcranial electrical stimulation (TES) and direct cortical stimulation (DCS). ⋯ This method shows the ability to continuously monitor the functional integrity of corticobulbar pathways, vagal nucleus and laryngeal nerves.

A realistic simulation exploiting real cortical sources identified from non-invasive extra-cranial recordings in healthy subjects has been considered in order to select the most robust procedure for choosing the correct order of multivariate autoregressive (MVAR) models. Different signal-to-noise ratios filter settings and sampling rates were also tested on the estimate of functional connectivity among the network nodes, in simulated and real cases. ⋯ Correct MVAR model order choice and band filtering play an important role for the correct network connectivity estimate.
