  • Neural and hormonal mechanisms in aggression
    • Neurotransmitters
      • Dopamine
      • Serotonin
        • Low levels of serotonin in the brain are  known to increase implusive behaviour, aggression and violent sucides.
          • Maan et al(1990) gave 35 healthy subjects dexfenfluramine (known to deplete serotonin). Using a questionnaire to assess hostility and aggression levels, they found dexfenfluramine in males is associated with an increase in hostility and aggression scores.
    • Hormonal mechanisms
      • Cortisol
  • Dopamine is less established with aggression however there is evidence to suggest that a link exists, high levels of dopamine is assocaited with aggression.
    • Dopamine
  • Lavine (1997), antipsychotics (reduce dopamine activity in the brain) reduces aggressive behaviour.
    • Dopamine is less established with aggression however there is evidence to suggest that a link exists, high levels of dopamine is assocaited with aggression.
    • Hormonal mechanisms
      • Cortisol
    • Testosterone
