1. A device for spinal cord stimulation, configured for securing to the dura surrounding the spinal cord of a subject, the device including the following components:
a plurality of electrodes;
wire leads configured to electronically connect the electrodes to a signal source outside the dura; and
a means for securing the device to the dura such that the electrodes are in direct contact with the cerebrospinal fluid (CSF) within the subdural space but not in direct contact with the spinal cord itself.
