Placement of respiratory monitoring devices. The measurement device for VPT was locked in place in the stereotaxic frame in front of the animal’s nose, so that the sensor was 1 to 5 mm from the nostril. The sensor for ACC was glued to the shaved chest wall using a flexible dental epoxy. WBP used an enclosed plastic chamber that completely surrounds the animal’s body, with subtle air displacements being picked up by pressure sensors in the system. (The isoflurane delivery method is not shown in this figure to highlight the positioning of the VPT sensor.)
