Independent regional control tone in the human brain
Researchers at the University of California, San Francisco found that there is a separate area in the frontal lobe of the human brain that controls the throat and regulates the tone of speech and singing. The two main functions of the throat are to make sounds and adjust the tone. Human beings are the only primates that can express their emotions and meanings by consciously controlling the tone. Previously, this ability was thought to be determined by the anatomical structure of the throat. But recent research shows that the evolution of neural activity on the regulation of laryngeal muscle may play a key role in language behavior and become the driving force for human language development. A study published in the latest issue of the American Journal of Cellology shows that the "dorsal laryngeal motor cortex" region between the area controlling the hand and mouth in the frontal lobe of the brain is associated with tone control. The researchers asked 12 volunteers to repeat the phrase "I never said she stole my money", each time by changing the tone of a word to express emotions and semantics such as exclamation, condemnation and inquiry. The researchers found that when the volunteers uttered the highlighted words, the activity of the "dorsal laryngeal motor cortex" increased, indicating that the region was associated with tone. The researchers say that the brain regulates the tone by controlling the throat muscles. When the gas passes through the throat, one can adjust the tension to control the vibration speed of the vocal cords. Just like the strings of the guitar, the contraction of the throat muscles accelerates the vibrations, giving off different tones. The research team next plans to study whether the process of "reverse design" of the human brain to control the tone, that is, by observing the neural activity, predicting the tone of the speaker's sentence, and judging the meaning of the emphasis they want to emphasize.
