Dipole Source Analysis of Laser-Evoked Subdural Potentials Recorded From Parasylvian Cortex in Humans

Hagen Vogel, John D. Port, Fred A. Lenz, Meiyappan Solaiyappan, Greg Krauss, Rolf-Detlef Treede
2003 Journal of Neurophysiology  
These findings suggest that the nociceptive area in human parasylvian cortex that is activated most rapidly by noxious heat pulses may be separate from the tactile SII area. Apkarian AV and Shi T.  ...  Dipole source analysis of laser-evoked subdural potentials recorded from parasylvian cortex in humans. J Neurophysiol 89: 3051-3060, 2003; 10.1152/jn.00772.2002.  ...  In summary, multiple lines of evidence from electrophysiological and imaging studies in humans indicate that parasylvian cortex is prominently involved in the processing of nociceptive stimuli.  ...

Left-hemisphere dominance in early nociceptive processing in the human parasylvian cortex. Neuroimage 20, 441-454.  ...  A left hemisphere dominance has been reported for the sensory dimension of pain (Schlereth, T. et al., 2003) , whereas right hemisphere dominance was observed for the affective dimension (Pauli, P. et  ...

How Do Brain Areas Communicate During the Processing of Noxious Stimuli? An Analysis of Laser-Evoked Event-Related Potentials Using the Granger Causality Index

Thomas Weiss, Wolfram Hesse, Mihaela Ungureanu, Holger Hecht, Lutz Leistritz, Herbert Witte, Wolfgang H. R. Miltner
2008 Journal of Neurophysiology  
Several imaging techniques have identified different brain areas involved in the processing of noxious stimulation and thus in the constitution of pain.  ...  This result was interpreted as a directed interaction between the anterior cingulate cortex and the secondary somatosensory cortex and the insula, structures that are significantly involved in the constitution  ...  and Mauguière 2003) dominates the processing of the posterior INS.  ...

Changes in Sensory Hand Representation and Pain Thresholds Induced by Motor Cortex Stimulation in Humans

B. Houze, C. Bradley, M. Magnin, L. Garcia-Larrea
2012 Cerebral Cortex  
Here, we assessed in healthy volunteers the ability of 2 modes of motor cortex rTMS commonly used in pain patients to induce changes in pain thresholds and plastic phenomena in the S1 cortex.  ...  partly counterbalance the plasticity induced by a nerve lesion, and thus substantiate the use of rTMS to treat human pain.  ...  This view is supported by the fact that primary somatosensory cortex is not a crucial region for the processing of nociceptive afferents: <4% of spinothalamic system projections may reach S1, while >70%  ...

Statistical Modeling and Analysis of Laser-Evoked Potentials of Electrocorticogram Recordings from Awake Humans

Zhe Chen, Shinji Ohara, Jianting Cao, François Vialatte, Fred A. Lenz, Andrzej Cichocki
2007 Computational Intelligence and Neuroscience  
This article is devoted to statistical modeling and analysis of electrocorticogram (ECoG) signals induced by painful cutaneous laser stimuli, which were recorded from implanted electrodes in awake humans  ...  Statistical hypothesis tests were also applied in various experimental setups. Experimental results reported herein also confirm previous findings in the neurophysiology literature.  ...  Subdural electrode grids were planted over the frontal-centralparasylvian cortex (no. 1-64 channels) and the medial wall of the left hemisphere (no. 65-80 channels).  ...
