A man was injured in an accident. Part of his brain was damaged.
After the accident, he could not form any new memories. He could still walk normally, keep his balance and speak.
Scientists studied the man for many years. This type of study is called a case study.
Suggest which part of the brain was damaged.
Give a reason for your answer.
Explain why it is difficult to use case studies like this to find out what each part of the brain does.
Scientists cannot deliberately damage part of the brain of a healthy person to find out what it does.
Explain why, and suggest one other method scientists could use to investigate brain function.
Suggest why getting consent can be an ethical issue in studies of patients with brain damage.
