Laboratory study using concurrent 64-channel EEG, polysomnography, and a novel optical sensor (the “Sentiometer”) to test whether a purely optical signal can track the presence and quality of conscious experience across sleep, perception, gameplay, and meditation tasks.

Updated 05/18/26 · By grantmaking.aiSentiometer: Validating Novel Optical Detection of Consciousness is a funded protocol in which healthy adults complete a 4.5-hour laboratory session combining auditory, visual, gameplay, and meditation paradigms followed by a monitored nap. Throughout the session, participants wear an EEG cap, polysomnography sensors, and an investigational optical device while researchers probe whether the optical signal tracks sleep-stage transitions, target detection, perceptual thresholds, and the content of visual experience, or instead overlaps with existing neural measures. The study is conducted at IACS’s Santa Monica lab with support from Senzient, Inc., and is currently beginning participant recruitment.
Theory of Change
Updated 05/18/26 · By grantmaking.aiIf the Sentiometer’s optical signal reliably covaries with established neural markers of conscious state and content, it could provide a non-invasive, portable biophysical channel for detecting consciousness that complements or augments current EEG and neuroimaging techniques.
