Probing the role of serotonin in neuropathic pain with flexible carbon microelectrode arrays
PROJECT SUMMARY Antidepressants have been front-line treatments for chronic pain for years. However, clinical efficacy of selective serotonin reuptake inhibitors (SSRI’s) has been moderate and highly variable across different conditions, which calls for a deeper understanding of 5-HT’s role in modulating pain, in an anatomical and receptor-specific manner. One area of recent interest is the amygdala. After neuropathic injury, neural activity in the amygdala changes during the chronification process, while changes in 5-HT have also been detected. Inhibition of the 5-HT2C receptor in the basolateral nucleus of the amygdala (BLA) “permits” SSRI-induced reduction of pain in rodents. In…
