The operational definition of aggression may be influenced by moral or political opinions. For example, the axiomatic moral vision, called the principle of non-aggression, and the political rules that govern one country`s behaviour towards another. [15] Some forms of aggression may also be sanctioned in competitive sport or in the workplace and others may not (see assault in the workplace). [16] Aggressive behaviours are linked to adjustment problems and several psychopathological symptoms such as antisocial personality disorder, borderline personality disorder and intermittent explosive disorder. [17] In mammals, the hypothalamus and peridutaire grey of the central brain are critical areas, as shown by studies of cats, rats and monkeys. These areas of the brain control the expression of the behavioral and autonomous components of aggression in these species, including vocalization. Electrical stimulation of the hypothalamus causes aggressive behavior[71] and the hypothalamus has receptors that help determine aggressiveness levels based on their interactions with serotonin and vasopressin. [72] In rodents, activation of neurons experimenting with estrogen receptors in the ventrolar part of the ventromic hypothalamus (VMHvl) was found to initiate aggression in both men and women. [73] [74] Midbrain areas involved in aggression have direct connections with the nuclei of the brain that control these functions and with structures such as the amygdala and prefrontal cortex. Many researchers focus on the brain to explain aggression.
Many circuits within neocortic and subcortic structures play a central role in controlling aggressive behaviours, depending on the type, and the exact role of the pathways may vary depending on the nature of the trigger or intent. [70] [3] From this point of view, there are no concepts such as persuasiveness, aggression, violence and criminal violence, which exist as buildings in their own right, but along a continuum where moderate levels of aggression are most adaptable. [36] These scholars do not view this as a trivial difference, as they find that the aggressiveness measures of many traditional researchers can measure results in the lower continuum, at adaptable levels, but they generalize their results to non-adaptive levels of aggression and thus lose accuracy. [165] In mice, the candidate genes for differentiating aggression between the sexes are the Sry gene (sexdetermining region Y) which is found on the Y chromosome and the Sts gene (steroidal sulfatase). The Sts gene encodes the sulphate sulphate enzyme that is essential for regulating neurosteroid biosynthesis. It is expressed in both sexes, is correlated with levels of aggression in male mice, and increases dramatically in women after participation and during breastfeeding, depending on the onset of maternal aggression. [76] At least one study found a possible epigenic signature (i.e., a decrease in methylation at a given location of cpG in the promoter region) of the 5-HT3a serotonin receptor associated with maternal aggression in human subjects. [80] Most ethologists believe that aggression has biological benefits. Aggression can help an animal secure territory, including resources such as food and water. Aggression between men often occurs to ensure mating opportunities, and leads to the choice of healthier/stronger animal.
Assaults can also occur to protect themselves or offspring. [24] Aggressiveness between groups of animals may also have benefits; For example, hostile behaviours may force an animal population to enter a new area where the need to adapt to a new environment may lead to increased genetic flexibility. [25] In a non-mammalian example of aggression-related genes, the sterile gene in fruit flies is a critical determinant for certain sexually dimorphic behaviours, and its artificial change may lead to reversing male and female stereotypes in combat.
