Article Synopsis
  • Preclinical drug development for visceral pain primarily uses restrained rodents to study pain responses, but the relevance to human pain experiences remains uncertain.
  • The study involved male rats undergoing colorectal distension (CRD) while measuring abdominal EMG and cerebral blood flow (rCBF) via advanced techniques.
  • Results showed that CRD induced notable increases in both EMG activity and behavioral pain scores, with rCBF changes observed in various brain regions associated with sensory and emotional pain processing.
  • This suggests that while CRD in rats can be a valid model for studying human visceral pain, there are more complex brain responses that traditional pain measures may not capture.
