Human single-neuron recordings have shown the power of measuring brain activity right at the source. But these studies are limited to short experimental windows in hospital settings.
Brain-computer interfaces (BCIs), on the other hand, are implanted long term in people with conditions such as epilepsy or ALS, helping them to function while also offering researchers a glimpse into neural activity in day-to-day life. This approach is decoding how the human brain plans and executes speech, revealing the similarities and differences between overt and intended speech and the role of regions such as the precentral gyrus.
