The perisylvian area related to motor speech is located in which hemisphere?

• A. Left hemisphere
• B. Right hemisphere
• C. Bilateral with left dominance
• D. Medial surface of the brain

Answer: (A)

Motor speech relies on language networks clustered around the Sylvian fissure, and these networks are typically dominant on the left side. In most people, Broca’s area (speech production) and Wernicke’s area (language comprehension) reside in the left hemisphere and are connected by pathways like the arcuate fasciculus, supporting planning and execution of speech. That’s why the perisylvian area related to motor speech is located in the left hemisphere. While some individuals—often left-handed or with different brain organization—may show more bilateral or atypical patterns, the common and most accurate answer is the left hemisphere. The right hemisphere is not typically the dominant region for motor speech, and the perisylvian language network is not located on the medial surface.
