Which physician is credited with studying Tan, the patient associated with Broca?

• A. Paul Broca
• B. Carl Wernicke
• C. Sigmund Freud
• D. Ivan Pavlov

Answer: (A)

The main idea here is identifying who linked the patient known as Tan with a specific brain region responsible for language production. Paul Broca studied Tan’s case and found that his speech was severely limited, while comprehension could be preserved. After Tan’s death, an autopsy revealed a lesion in the left frontal lobe, an area now called Broca’s area. This discovery spearheaded the concept that particular cognitive functions—like language production—are localized to specific brain regions.

The other figures are associated with different contributions: Wernicke described language comprehension and a separate language area, Freud is known for psychoanalysis, and Pavlov for conditioned learning. So the physician credited with studying Tan is Paul Broca.
