Temple releases 23-person ‘Brain Flow’ study awaiting peer review, Inc42 reports

Inc42 reports that Temple’s first validation study involved 23 healthy adults and compared its proprietary Brain Flow metric with TCD ultrasound measurements of cerebral blood-flow velocity. Researchers found a median within-subject correlation of around 0.8 across two controlled activities. The study is a preprint awaiting peer review. Inc42 says the findings do not establish that Temple can measure absolute brain blood flow or diagnose medical conditions, and further studies using different measurement techniques are needed.
