Department of Functional Neurology and Epileptology, Federative Institute of Neurosciences (INSERM IFR 19, Bron, France
Epilepsia 47:98-107. 2006..CONCLUSIONS: This study shows that ictal changes in PuM activity are frequently observed during temporal lobe seizures and suggests that this thalamic nucleus might participate in their propagation...

INSERM U879, Intégration centrale de la douleur, F 69677 Lyon, France
Presse Med 37:315-40. 2008..This suggests that their role in experimental allodynia would likely be reactive and protective, and that inability to generate their activation may contribute to the clinical expression of neuropathic pain...
