The authors further concluded that "the 2D:4D digit ratio is neither strongly nor reliably related to aggressive or violent behavior". [ 3 ] Other researchers have also pointed out the fact that the 2D:4D digit ratio, which is the method most often used to relate prenatal testosterone to future behaviors, is a rough and unreliable measure of ...
Aggressive behavior has been associated with abnormalities in three principal regulatory systems in the body: serotonin systems, catecholamine systems, and the hypothalamic-pituitary-adrenocortical axis. Abnormalities in these systems also are known to be induced by stress, either severe, acute stress or chronic low-grade stress. [34]
A variant of the gene that encodes the neurotransmitter metabolizing enzyme monoamine oxidase-A (MAOA), which relates to neural systems involved in aggression, plays a key role in regulating behavior following threatening events. Brain imaging studies show patterns of arousal in areas of the brain that are associated with aggression in response ...
Agonistic behaviour is a result of evolution, [5] and this can be studied in a number of species facing different environmental pressures. Though agonistic behaviours can be directly observed and studied in a laboratory setting, it is also important to understand these behaviours in a natural setting to fully comprehend how they have evolved and therefore differ under different selective ...
