Genetically dependent modulation of serotonergic inactivation in the human prefrontal cortex

Previous research suggests that genetic variations regulating serotonergic neurotransmission mediate individual differences in the neural network underlying impulsive and aggressive behaviour. Although with conflicting findings, the monoamine oxidase-A (MAOA) and the serotonin transporter (5HTT) gene polymorphisms have been associated with an increased risk to develop impulsive and aggressive behaviour. Double knock-out mice studies have also...
