Image Wikipedia, Wernicke's area Which brain area should we observe? If we want to make the Brain-Computer Interface (BCI)? Maybe the best point would be the neural tracks that transport information to the facial and throat muscles from the sensorimotor brain lobe. The problem is that observing this kind of structure requires an extremely high accuracy. The complete BCI requires deep knowledge of the brain activity and its internal and external communication. The key role in communication is in the Broca's and Wernicke areas. But what area should we observe, if we want to transmit thoughts to the computer? Natural selection is the brain lobe that produces speech. Transforming speech to text and driving it to the AI is simple. But if we want to take that text straight from the brain, we must realize that speech is a product of the cooperation of multiple different brain lobes. And that is the key problem that BCI sensor creators must solve. The Neuralink chip observes the Bro...
