This thesis contrasts their roles in acute versus chronic pain and explores interactions with core functions such as respiration. In acute injury, ON-cell activity drives hyperalgesia, but in chronic inflammation, ON-cell inhibition exacerbates pain, indicating distinct mechanisms. Respiratory monitoring revealed that ON-cells modulate both pain and respiration, while OFF-cells primarily mediate analgesia. Opioid effects in the RVM confirmed separable pathways for analgesia and respiratory depression. These findings advance understanding of RVM physiology and suggest strategies for developing non-respiratory-depressant analgesics.}, url = {http://digitalcollections.ohsu.edu/record/792}, doi = {https://doi.org/10.6083/M48G8HPB}, }
