Research Topic: Optogenetic approaches to dissect neural circuitry of pain

The neuronal circuitry that drives tactile allodynia, where innocuous touch is perceived as painful, is a common phenomenon associated with chronic spinal and trigeminal pain.  In healthy subjects, information about light touch versus mechanical pain is transduced by Aβ mechanoreceptors and C-fiber nociceptors, respectively, whose cell bodies are located in dorsal root and trigeminal ganglia. In chronic neuropathic states, however these neurons undergo abnormal circuit properties such that touch mechanoreceptors may now signal pain. My long-term goal is to identify the neural circuits responsible for chronic pain associated phenotypes such as allodynia, in both the spinal and trigeminal pain systems. My overall objective in my research is to delineate the role of both Aβ touch neurons and C-fiber nociceptors in mechanical allodynia using a molecular optogenetic approach.
