Abstract

Pain is a prevalent symptom of Parkinson's disease, and is effectively treated by deep brain stimulation of the subthalamic nucleus (STN). However, the link between pain and the STN remains unclear. In the present work, we report that STN neurons exhibit complex tonic and phasic responses to noxious stimuli using in vivo electrophysiology in rats. We also show that nociception is altered following lesions of the STN, and characterize the role of the superior colliculus and the parabrachial nucleus in the transmission of nociceptive information to the STN, physiologically from both structures and anatomically in the case of the parabrachial nucleus. We show that STN nociceptive responses are abnormal in a rat model of PD, suggesting their dependence on the integrity of the nigrostriatal dopaminergic system. The STN-linked nociceptive network we reveal is likely to be of considerable clinical importance in neurological diseases involving a dysfunction of the basal ganglia.

Ethics

Animal experimentation: In accordance with the policy of Lyon1 University, the Grenoble Institut des Neurosciences (GIN) and the French legislation, experiments were done in compliance with the European Community Council Directive of November 24, 1986 (86/609/EEC). The research was authorized by the Direction Départementale des Services Vétérinaires de l'Isère - Ministère de l'Agriculture et de la Pêche, France (Coizet Véronique, PhD, permit number 381003). Every effort was made to minimize the number of animals used and their suffering during the experimental procedure. All procedures were reviewed and validated by the ""Comité éthique du GIN no 004"" agreed by the research ministry (permits number 309 and 310).
