"Wave" fury This finding is consistent with the conclusions of the psychologist from the University of Alabama Tsillmanna Dolph, who has studied the anatomy of anger and rage during the long, carefully executed experiments. Given that the source of anger is rooted in the fighting wing of response by the type of "fight-or-save", there is nothing surprising in the fact that Tsillmann found universal trigger anger - a sense of danger. Danger signals can serve as not only a direct physical threat, but also - and that happens much more frequently - a symbolic threat to self-esteem or self-esteem, if a person cost rude or unfair, if it insulted or humiliated, if he is defeated in pursuit of some important target. These perceptions cause a surge of activity of the limbic system, have a twofold impact on the brain. This surge, on the one hand, is the release of catecholamines , which provide quick, episodic burst of energy, enough to "single decisive action," as it formulates Tsillmann, "such as a fight or escape". This energy emission lasts several minutes, during which it prepares the body for a good fight or retreat quickly, depending on how the emotional brain assesses the opposition.
