My project investigates the role of the primary (S1) and secondary (S2) somatosensory cortices, the insula, and the anterior cingulate cortex (ACC) in human pain perception. To this end, I use intracerebral EEG recordings performed in patients for the presurgical evaluation of intractable epilepsy, combined with advanced signal-processing methods.

Research projects

Intracerebral EEG recordings to investigate the role of the insula in nociception

Investigators : Giulia Liberati, Susana Ferrao Santos, André Mouraux. A widely accepted notion is that one particular region of the “pain matrix”, the insula, plays a specific role in the perception of pain, and the activity recorded from this region is often considered as an objective signature of...

Questioning the functional significance of the “pain matrix”

Investigators : André Mouraux, Giulia Liberati, Elisabeth Colon. Neuroimaging and neurophysiological studies have shown that transient nociceptive stimuli elicit responses in an extensive cortical network including somatosensory, insular and cingulate areas, as well as frontal and parietal areas. A...
