Marcus is a repeat offender who has been convicted of several violent assaults. A neurological assessment using an fMRI scan reveals that Marcus has significantly reduced grey matter volume in his amygdala. Marcus also demonstrates an inability to recognize facial expressions of fear or distress in others, and psychometric testing indicates he does not associate his aggressive actions with negative consequences.
Explain how amygdala dysfunction can be used to explain Marcus's criminal and violent behaviour.
