In recent years, new indications have been studied for severe and drug-resistant forms of several neurological and neuropsychiatric pathologies. Its non-lesional, reversible and customizable nature make it a therapy of choice.\n\nHowever, several factors are currently slowing down the evolution and optimization of SCP.\n\nThe identification of objective, quantifiable and predictive criteria for the therapeutic effects of stimulation would allow an acceleration of the individualized identification of the therapeutic parameters of SCP. The surgical procedure for implanting the stimulation equipment is carried out in several stages, which offer unique opportunities to acquire individual imaging or electrophysiology data that are potentially predictive of the therapeutic effect of DBS. In order to continue the optimization of DBS procedures, and therefore to maximize its therapeutic effects, it seems crucial to us to take advantage of all the neurophysiological data likely to be collected during this procedure. Furthermore, given the multiplication of indications for SCP, it seems necessary to highlight specific markers. Thus, the use of neurocognitive and\u002For motor tests specific to each pathology and coupled with electrophysiological recordings and anatomical and functional examinations would make it possible to highlight specific functional biomarkers predictive of therapeutic effects.",[114],"Pathology Requiring Deep Brain Stimulation Therapy",[116,117,118,119,120,121],"DBS","LFP","MUA","MEG","IRM","cognitive tasks","2026-09-17",{"date":124,"type":125},"2026-09-18","ACTUAL",{"date":127,"type":125},"2024-09-18",{"date":129,"type":109},"2036-04-25",{"name":5,"class":6},2]
