When the animals engaged in OR during test-pulse stimulation, immediately after cessation of the task, fEPSPs became persistently depressed (n = 10).
Our results show that VOC exposures remain airborne even after the cessation of cleaning tasks, suggesting potential exposure to anyone entering the room shortly after cleaning.
TVOC time concentration profiles indicated that exposures above background level remained present for about 20 minutes after cessation of the tasks.
Real time TVOC concentration profiles after the cessation of cleaning tasks indicated that it takes more than 20 minutes after cleaning for exposures to decline to background levels.
However, children with high BPb levels (1 SD above the mean) did not exhibit a cortisol decrease after cessation of the stressor task (Gump et al. 2008).
Upon cessation of the stressful task, heart rate (p < 0.001), respiration frequency (p < 0.001) and muscle activity in the trapezius (p < 0.003) and the frontalis (p < 0.002) decreased significantly (50 60 min vs. 65 75 min).
However, systolic and diastolic blood pressure, finger skin blood flow and muscle activity in the splenius and temporalis muscles did not change significantly upon cessation of the stressful task (50 60 min vs. 65 75 min and 50 60 min vs. 85 95 min, p > 0.10).
Fifteen minutes after the cessation of the cold pressor task a post-stress saliva sample was collected, after which participants began the computerized risk task.
It is possible that chewing gum has a transient positive effect, but only after cessation of chewing, since chewing while on task can have a negative effect [ 15, 16].
Finally, jet-lagged animals remained unable to acquire the learning task one month after cessation of the jet lag when ZT and CT should be consistent between jet lag and control conditions.
For example, 2 h of isoflurane-nitrous oxide anesthesia impairs acquisition of a hippocampal-dependent spatial memory task 48 h after cessation of anesthesia in young rats and at least 2 weeks after cessation of anesthesia in aged rats (Culley et al., 2004a, b; Crosby et al., 2005).
