The instruments
Classic laboratory paradigms and validated self-report scales, implemented in the browser. Every task states the brain regions it engages; every result is yours alone — computed locally, exportable as CSV, remembered only in this browser.
Region nomenclature follows Mai, Majtanik & Paxinos, Atlas of the Human Brain, 4th ed. (2016). Functional descriptions summarise established systems neuroscience, and are educational context — not diagnostic claims.
Digital experiences
Beyond measurement: experiences that act on the brain. Each one states the regions it touches, the mechanism, and the instrument that reads its effect. An experience without its measurement pair is named here, not shipped.
Cortical and subcortical engagement
