Charles Whitman (1966): He killed 13 people, after killing his mother and wife. He left a note asking doctors to examine his brain, as he thought something was making him aggressive. He a brain tumour pressing on his amgdala.
Difficulties Researching The Brain.
· Cut brain open to see inside.
· Damage areas and see if it affects aggression.
· Use animals instead.
· Researchers study animals instead of humans because of ethics.
· Damaged amygdala - affects…
