Pierre Paul Broca studied the brains of patients with articulatory language deficits and reported that articulatory function is localized in the frontal cortex of the left hemisphere. This discovery of functional localization laid the foundation of neuroscience in general and marked the beginning of brain science of language. According to recent reexaminations of the patients' brains, the lesions responsible for apraxia of speech may instead involve the insula or medial fiber connections. Based on the results of functional neuroimaging and lesion studies, we have identified a "grammar center" in the left inferior frontal gyrus, long regarded as "Broca's area." Therefore, the traditional view that Broca's area is the sole center of speech production requires revision.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
