Low levels are associated with an append in voluntary behaviour, aggression and even violent suicide. secernate supporting the importance of serotonin in aggressive behaviour was found in research using vervet monkeys. capital of North Carolina et al (1991) found that if serotonin levels were reduced by modify their diet, there was an annex in aggressive behaviour whereas an increase in serotonin levels resulted in a decrease in aggressive behaviour suggesting the difference in aggression was receivable to the serotonin levels. Other research demonstrating the link between junior-grade levels of serotonin and aggression was done by Bond (2005).
He found that antidepressants which increase serotonin levels reduced irritability and impulsive aggression.
The link between dopamine and aggressive behaviour is not as well established. However, increased levels of dopamine stimulated by amphetamines have shown an increase in aggression whereas antipsychotic drugs that reduce dopamine levels have been shown to reduce violent behaviour (Lavine and Buitelaar). Interestingly, a study by Couppis and Kennedy (2008) using mice, found that dopamine acts as a positive reinforcer in the response to an aggressive event. This would lead to individuals seeking out aggressive behaviour because they would pay a rewarding sensation from...If you want to get a full essay, order it on our website: Orderessay
