Timeline of experiments. Small arrows indicate bolus injections of phenylbiguanide (PBG) in increasing doses (1–8 µg/kg) into the right atrium in 2.5 min intervals. Double large arrows represent bilateral microinjections into the nucleus tractus solitarii (NTS) of: A2a adenosine receptor agonist CGS-21680 (0.2, 2 and 20 pmol in 50 nl), and selective A2a adenosine receptor antagonist, ZM-241385 (40 pmol in 100 nl).
