Abstract: Broca's area: monkeys too In 1861 a physician, Paul Broca, described a patient with speech problems who said only one word: ‘tan’. When the patient died, brain damage was discovered in part of the left frontal cortex, which became known as Broca's speech production area, or human architectronic area 44. Today there is controversy as to whether nonhuman primates possess a comparable cortical area. Now Petrides et al. show that monkeys do possess such an area, and that it is involved with facial musculature. The area may have evolved to control the jaw and other actions including those related to communication.
