Smart laser dimmer cuts neural crosstalk in brain-circuit imaging and control

MedicalXpress | 四月 22, 2026

A cross-disciplinary team led by Prof. Qu Jianan from the Department of Electronic and Computer Engineering and Prof. Julie L. Semmelhack from the Division of Life Science at The Hong Kong University of Science and Technology (HKUST) has developed a powerful laser control technique. Functioning as a smart dimmer, it can selectively adjust the brightness of every pixel during laser scanning, and prevent unintended neural activation, thereby significantly enhancing the precision of all-optical brain manipulation and imaging.
