Neuropathic pain is a debilitating condition which is often refractory to traditional pain medication and treatment. To understand how pain is processed in individuals suffering from neuropathy, we must examine transmission pathways in the spinal cord and brainstem using a neuropathic patient population. Spinal fMRI studies, using a HASTE sequence, were carried out in individuals diagnosed with carpal tunnel syndrome (CTS). Our findings show that neuropathic pain is associated with neuronal activity in regions that differ from typical pain transmission pathways, indicating that the manner in which neuropathic pain is processed differs from that in healthy controls.
