Despite a large body of work implicating the vlPAG in pain modulation, the neuron type specific activation by acute and persistent inflammation has not been identified. This hypothesis posits selective MOR expression on GABAergic interneurons, however, several studies have revealed less targeted MOR expression, prompting us to determine whether MOR expression maps onto physiologically distinct neuron types. 000009317 542__ $$fIn copyright - single owner 000009317 650__ $$aPain Perception$$039340 000009317 650__ $$aPain Management$$039572 000009317 650__ $$aElectrophysiology$$018311 000009317 6531_ $$aneuroscience 000009317 691__ $$aSchool of Medicine$$041369 000009317 692__ $$aVollum Institute$$041509 000009317 7001_ $$aMcPherson, Kylie B. 000009317 8564_ $$9073d8f08-e325-473d-b785-be768d8e1599$$s5295312$$uhttps://digitalcollections.ohsu.edu/record/9317/files/McPherson.Kylie.2021.pdf 000009317 905__ $$a/rest/prod/vd/66/w0/63/vd66w063w 000009317 909CO $$ooai:digitalcollections.ohsu.edu:9317$$pstudent-work 000009317 980__ $$aTheses and Dissertations
