It has been displayed that impulsive behavior and aggression have already been associated with having low levels of serotonin. Evidence intended for the function of serotonin comes from the use of medicines that increase levels of serotonin in the human brain, such as antidepressants. In medical studies, В antidepressant drugs which in turn increase serotonin levels also tend to decrease irritability and impulsive hostility.

Analysis by Couppis and Kennedy found dopamine may be a result of aggressive conduct rather than a cause. В They suggest that persons may find aggressive runs into because dopamine is produced as a positive reinforcer every time they engage in hostile behaviour. A meta-analysis of studies that had examined neurotransmitter amounts in asocial children and adults identified lower levels in those described as 'aggressive' but zero difference in dopamine levels for these individuals when compared to 'normal' individuals.

You sex body hormone testosterone can be produced in you testes and the adrenal cortex. It really is thought to increase levels of hostility from young adulthood onwards. It is thought that testosterone may possibly influence parts of the brain that control behavioural reactions, including the amygdala and the hypothalamus. Testo-sterone influences the levels of different hormones which are...
