Deep dives

The Discovery of Language Areas

The historical understanding of language areas in the brain was based on observations by neurologists like Broca and Wernicke. Broca observed a patient who could only say the word 'tan' and found that the frontal lobe was responsible for articulating speech. Wernicke observed patients who produced fluent but nonsensical speech and had difficulty understanding language, and identified a region in the posterior temporal lobe as important for language comprehension. These observations led to the belief that language was lateralized to the left hemisphere in most individuals.
