Several imaging techniques have identified different brain areas involved in the processing of noxious stimulation and thus in the constitution of pain. However, only little is known how these brain areas communicate with one another after activation by stimulus processing and which areas directionally affect or modulate the activity of succeeding areas. One measure for the analysis of such interactions is represented by the Granger Causality Index (GCI). In applying time-varying bivariate and…

EEG analysis reveals widespread directed functional interactions related to a painful cutaneous laser stimulus.
Results demonstrated that EEG channels with poststimulus ERC interactions were consistently different during the laser stimulus versus the electric stimulus, and scalp EEG frontal channels play a driver role while parietal temporal channelsplay a receiver role during both tasks, although this does not prove that these channels are connected.
Functional integration within the human pain system as revealed by Granger causality
Pain is a complex experience subserved by an extended network of brain areas. However, the functional integration among these brain areas, i.e., how they interact and communicate to generate a
Causality analysis of P300 recordings focused on the localization of active brain areas
The obtained results using causality can validate the analysis performed by an specialist, and they demonstrate the causal interactions between electrophysiological signals of different sites of the cortex, occurring during cognitive processes related with ERP.
Spectral and spatial changes of brain rhythmic activity in response to the sustained thermal pain stimulation
The results imply the possibility of using noninvasive EEG to predict pain intensity and to study the underlying pain processing mechanism in coping with prolonged painful experiences, and may provide an objective measure for better pain management in clinical applications.
Hypnotizability-Related Effects of Pain Expectation on the Later Modulation of Cortical Connectivity
Findings suggest a lower impact of nociceptive stimulation in highs than in lows, which could be relevant to the development of pain-related individual traits.
Trial by trial, machine learning approach identifies temporally discrete Aδ- and C-fibre mediated laser evoked potentials that predict pain behaviour in rats
It is demonstrated that both C- and Aδ-fibres contribute to rodent LEPs and concomitant behavioural responses, providing a real-time assay of specific fibre function in conscious animals.

A four-dipole model was developed using data following left- hand stimulation and yielded good fits for right-hand and left-foot stimulation data and, in addition, another set of left-hand data obtained with different electrode spacing in a different group of subjects (residual variances from 2.8% to 3.3%).
Role of Operculoinsular Cortices in Human Pain Processing: Converging Evidence from PET, fMRI, Dipole Modeling, and Intracerebral Recordings of Evoked Potentials
This multimodal study provides cross-validated spatial and temporal information on the pain-related processes occurring in the operculoinsular region, which thus appears as a major site for the early cortical pain encoding in the human brain.
Laser-evoked potentials: exogenous and endogenous components.
Dipole source analysis of laser-evoked subdural potentials recorded from parasylvian cortex in humans.
The 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.
Brain generators of laser-evoked potentials: from dipoles to functional significance
Generator mechanism of pain-related evoked potentials following CO2 laser stimulation of the hand: scalp topography and effect of predictive warning signal.
The findings suggest that P2 is generated by a different mechanism from N2 and is most likely associated with pain-related cognitive function, suggesting that an increased attention of the subject to the stimulus influenced the generator mechanism of the P2 component.
