Figure 1. Recording of arterial pressure (AP) and heart rate (HR) from a single unrestrained male Wistar (A) and SHR (B) rat before, during, and immediately following exposure to unrestrained AJS.
Gray and white horizontal bar represents the 20 min duration of air jet stress (AJS), including an initial 5 min of randomly directed AJS (white) and 15 min of sustained AJS in which the direction of air changes in 1 min intervals (gray). The total recording represents 35 min.
