Unmyelinated trigeminal pathways as assessed by laser stimuli in humans.
TLDR
The trigeminal territory yields rewarding LEP findings owing to the high density of thermal receptors and, because the short conduction distance, minimizes the problem of signal dispersion along slow-conducting unmyelinated afferents. Expand
Pain-related modulation of the human motor cortex
TLDR
Further studies are required to assess the effects of pain on the motor system in patients suffering from chronic pain, in order to develop innovative rational therapeutic strategies to reduce both pain and motor disability. Expand
Functional changes of the primary somatosensory cortex in patients with unilateral cerebellar lesions.
TLDR
These neurophysiological findings indicate that the primary somatosensory cortical processing is altered after contralateral cerebellar damage, and represent the first indication of a possible substrate for the reduction in cerebral blood flow observed in the parietal cortex after Cerebellar lesion.

Characterizing somatosensory evoked potential sources with dipole models: Advantages and limitations
TLDR
Although the effectiveness of dipolar source analysis should not be overestimated, dipole modeling provides a means to assess SEPs in terms of cerebral sources and voltage fields that they produce over the head. Expand
Dipolar sources of the early scalp somatosensory evoked potentials to upper limb stimulation Effect of increasing stimulus rates
TLDR
Dipolar source modelling in scalp medium nerve somatosensory evoked potentials recorded at 1.5-Hz eased the effect of an increasing repetition frequency on the activity of SEP dipolar sources, and found that the 10-Hz stimulus frequency reduced selectively the later of the two activity phases of the first perirolandic dipole.

Inhibitory effect of voluntary movement preparation on cutaneous heat pain and laser‐evoked potentials
TLDR
The results represent the first neurophysiological suggestion that physiological activation of the motor cortex, occurring during movement preparation, inhibits cortical pain processing by a centrifugal mechanism. Expand
Pain in chronic pancreatitis: the role of reorganization in the central nervous system.
TLDR
The findings indicate that pain in chronic pancreatitis leads to changes in cortical projections of the nociceptive system, which suggests a neuropathic component in pancreatic pain, which may influence the approach to treatment. Expand
Inhibition of biceps brachii muscle motor area by painful heat stimulation of the skin
TLDR
Findings suggest that CO2 laser pulses delivered on the hand are able to inhibit the arm proximal muscle motor area. Expand
Contact Heat Evoked Potentials to Painful and Non-Painful Stimuli: Effect of Attention Towards Stimulus Properties
TLDR
The results suggest that CHEPs represent a reliable functional measure of the nociceptive pathways and that they are generated by the activation of different cerebral areas involved in pain processing. Expand
The “human visceral homunculus” to pain evoked in the oesophagus, stomach, duodenum and sigmoid colon
TLDR
Findings reflect differences in pathways and brain processing of visceral nociceptive inputs coming from either upper or lower gut and may improve the understanding of the brain-gut axis in health and disease. Expand
