  Complex Traveling Waves May Reveal How the Brain Reorganizes Itself

  Researchers studying intracranial recordings found that brain activity can form more complex traveling waves than simple planar patterns, including source, sink, and spiral-like waves. The study suggests these wave patterns may help reorganize cortical activity in real time and differ across behavioral tasks.

  EEG study finds the brain can encode two speech streams at once during attention switches

  Researchers used EEG in a multi-speaker listening task to study how people switch attention between competing speech streams. The results suggest a brief overlap in neural tracking, where the new target stream is encoded before the old one fully disengages, alongside changes in alpha power and lexical-context updating.

  Meta Open-Sources Brain2Qwerty V2 for Noninvasive Brain-to-Text Decoding

  Meta has open-sourced Brain2Qwerty v2, a noninvasive brain-computer interface that decodes sentences from EEG or MEG brain signals. In reported evaluations, it reached 61% average word accuracy, substantially outperforming other noninvasive approaches at 8%.

  Meta shows non-surgical brain-to-text decoding

  Meta reports a research system that can decode brain activity into words and typed text without requiring surgery. The work suggests a potential communication aid for people with severe speech impairment, but it remains a laboratory research result rather than a consumer product.
