Mean (+/− SEM) heart rate orienting response recorded on the first trial for all groups. Heart rate was measured for 1 s prior to stimulus onset (baseline heart rate), during the 10 s olfactory stimulus, and for 5 s after stimulus offset. The data shown are changes in heart rate (beats-per-minute; BPM) from pre-stimulus baseline.
