• Post mortem - analysis of the brain after death, likely on those with a rare disorder
• Post mortem examinations may involve comparison to a neurotypical brain.
• An example of this technique is the work of Paul Broca, who examined the brain of a man who displayed speech problems when he was alive. It was subsequently discovered that he had a lesion in the area of the brain important for speech production that later became known as the Broca’s area.
