Hippocampal Stimulation in Chronic Low Back Pain

For the brain stimulation the investigators will use Repetitive Transcranial Magnetic stimulation (rTMS). Different stimulation conditions (hippocampal or sham) will be delivered in each round of stimulation (5 days). Repetitive TMS will be applied at 100% resting motor threshold intensity, 20 Hz pulse trains separated by 28-s inter-train intervals (\~20 minutes for the entire daily stimulation session). Stimulation parameters will be identical in both groups
