Stressor Categorization:Acute Physical and Psychological Stressors Elicit Distinctive Recruitment Patterns in the Amygdala and in Medullary Noradrenergic Cell Groups[J].European Journal of Neuroscience,2001,(07):1143-1152.doi:10.1046/j.0953-816x.2001.01733.x....
Although most brain areas and circuits are involved in these processes, and various brain circuits can trigger a stress response depending on the nature of the stressor, there are key regions that integrate stress signals in situations of (real or perceived) threat: the paraventricular nucleus of ...
to ensure that saliva was not contaminated, participants were asked to refrain from drinking alcohol 24 hours before the experiment, from performing intense physical exercise 2 hours before the experiment
A fire disaster, as a real-time stressor, would immediately activate amygdala functioning which would then integrate cognitive processing associated with emotionally salient stimuli. These steps would lead to an involuntarily attention to salient environmental events and result in the facilitation of ...
Acute stress is defined as a sudden or short time stressor (trauma, perceived threat, death of a loved one, job loss, etc.) as opposed to chronic stress—long time stressor (Fink, 2007, p. 192‑193). Acute stress with animal models is usually divided into physical (shock, cold, loud...
“wrapped” around the model. Examples of wrapped methods in the literature are: recursive feature elimination (RFE)44,71, forward feature selection (FFS)39,43,49, back feature elimination (BFE)43, and genetic algorithm (GA)40,56. Embedded methods look for an optimal subset of features ...

Here, we aimed to evaluate the effect of a cocoa-enriched diet on the physical performance, the ROS production by peritoneal macrophages, and the systemic immune function of rats submitted to intensive acute exercise, as well as to elucidate the involvement of cocoa fiber in such effects. 2. ...
By non-destructively observing heartbeat frequency before, during and after applying a stressor (physical restraint) for 10 min, we sought to determine: (1) the exact timing of the cardiac stress reaction; (2) the magnitude of heartrate elevation during stress; and (3) if the physiological ...
