Typical recordings showing the effects of microinjecting WAY into the mNTS (A) or the interstitial NTS (iNTS, B) on the apneic blockade by systemic DPAT challenge in two rats, respectively. VEH, local microinjection of vehicle; VEH+DPAT or WAY+DPAT, local microinjection of vehicle or WAY followed by systemic DPAT challenge. Arrows point to the onset of bolus injection of fentanyl into the right atrium. C: locations of microbeads microinjected into bilateral iNTS.
