Advancing noninvasive EEG with high spatiotemporal resolution through focused ultrasound

A research paper by scientists from Tianjin University proposed a noninvasive method for locating and decoding intracranial endogenous signals with high spatiotemporal resolution. The research paper, published on Apr. 9, 2025 in the journal Cyborg and Bionic Systems. High spatiotemporal resolution of noninvasive electroencephalography (EEG) signals is an important prerequisite for fine brain–computer manipulation. However, conventional scalp EEG has a low spatial resolution due to the volume conductor effect, making it difficult to accurately identify the intent of brain–computer manipulation. In recent years, transcranial focused ultrasound modulated EEG technology has increasingly become a research hotspot, which is expected to acquire…
