Pain and depression comorbidity causes asymmetric plasticity in the locus coeruleus neurons

Summary: There is strong comorbidity between chronic pain and depression. This study explores how this comorbidity occurs. The authors refer to published research that shows icv administration of anti-DBH-SAP or intra-LC administration of lidocaine dampened the evoked pain in conditions of long-term nerve-injury. However, icv injection of anti-DBH-SAP disrupts all noradrenergic nuclei (A1-A7), some of which contribute to sensorial hypersensitivity.
