Question

Quizplus · Accepted Answer

The discovery of the speech area of the brain was not based on asking if the loss of speech was caused by a stroke, but rather by comparing stroke victims who had difficulty speaking to those who did not. Broca looked for commonalities among those who were unable to speak and examined how their brain areas differed from others. He also investigated if the severity of the speech problem varied with the size of the affected brain area.
