Researchers will perform an autopsy to try to find any physical evidence for their study. Broca (1861) found that people with damage to the left frontal lobe were unable to create grammatically complex sentences. Despite this, his patients were able to understand speech from other people. Wernicke (1874), on the other hand, found that people with damage to the left posterior superior temporal gyrus had trouble with language comprehension. However, these patients, unlike Broca’s, were able to produce complex speech. Broca and Wernicke were able to study their patients, all of whom had previously suffered a stroke. After their patients died, the researchers completed an autopsy. Both researchers were able to provide evidence of localization of function in the brain. Post mortem studies provide an up-close view into functions of the brain, as well as physical evidence. They have a higher ecological validity due to their natural, real-life consequences, but because of this, they have no independent variables or dependent variables, and no controls. Researchers must also ensure the patient's’ privacy rights to keep within ethical guidelines. On another note, post-mortem studies are becoming less necessary, due to the uprising of technology, such as the EEG, PET, and fMRI. These technological advances are making studying a living brain possible, so waiting for a patient to die to see the inside of their brain is no longer
