Brain areas and aggression STRENGTH- Downer (1961)
Had one amygdala removed + optic nerve cut. Monkeys either had visual signals to detached or attached amygdala. Latter = more aggressive, former = more placid and calm. Supports that amygdala = involved in an aggressive response to a perceived threat

Brain areas and aggression STRENGTH- Blair, Colledge and Mitchell (2001)
Found patients with psychopathic behaviour patterns = have very similar neurocognitive functioning to patients who have suffered damage to the amygdala. However, single case studies = not representative.

Brain areas and aggression STRENGTH- Raine et al (1997)
Found lower activity in prefrontal cortex + differences in functioning of the limbic system in brain scans of murderers.

Brain areas and aggression STRENGTH- Swantje (2012)
Shows that self-reported aggression links with the size of the amygdala (smaller = more aggressive)

Brain areas and aggression WEAKNESS of Individual Differences
May have an effect: example: Phineas Gage- can't generalise as other people in different circumstances w/ similar damage may react differently. May be because the change in behaviour = due to his reaction to the facial disfigurement.

Brain areas and aggression WEAKNESS of generalisability
A lot of research on brain areas is done on animals, which can't be generalised to humans. For example: the prefrontal cortex is smaller in animals than it is in humans, affecting the credibility of the research.

Brain areas and aggression WEAKNESS- of specism
Whilst some argue that animals are put in pain from these experiments (having their brains lesioned) some argue it's of benefit to us. Bateson's Cube is use to determine the cost-benefit analysis.
