Study of the Location of Motor Cortical Stimulation Electrodes in Chronic Neuropathic Refractory Patients

Cortical stimulation has been used since 1991 to treat neuropathic pain. However, the underlying mechanisms are still incompletely understood and under-studied. In this protocol, the investigators aim to study the myeloarchitectonic and functional characteristics of areas activated by cortical epidural electrodes and to determine their relation to therapy response in chronic neuropathic refractory pain patients.
