Contactless optical decoding of cortical language responses via region-transferable speckle dynamics

2026-03-26

Abstract excerpt

<title>Abstract</title> <p>Remote decoding of human brain activity without surgery or physical contact remains a major challenge for brain-computer interfaces. Using laser speckle dynamics, we show that cortical responses during language processing can be decoded contactlessly. Across two independent experimental paradigms involving 17 healthy participants, 23 sessions, and 462 recordings, a classifier distinguis...
