Do you trust wearable technology to accurately monitor changes in your brain's blood flow?
Deepinder Goyal released findings from a validation study for the Temple BrainFlow wearable. The research measured the device against time-domain NIRS to ensure its readings align with brain blood volume.
Why it matters
The study sought to determine if the wearable accurately tracks brain blood volume while minimizing interference from scalp blood volume. This distinction is vital for non-invasive neurovascular monitoring in clinical settings.
The validation study included 60 participants tested across three distinct physiological challenges. BrainFlow measurements reached a peak correlation of 0.91 with brain blood volume during head-down tilt.
The players
Deepinder Goyal
Deepinder Goyal is a researcher who led the release of the validation study for the Temple BrainFlow device.
David Boas
Professor David Boas is an academic who guided the research process for the BrainFlow validation study.
The details
Researchers utilized three physical tests, including head-down tilt, stand-to-squat, and stand-to-supine movements, to compare BrainFlow data against time-domain NIRS measurements of oxygenated haemoglobin. The study results indicate that the device maintains a high correlation with brain activity while remaining distinct from superficial scalp interference.

Health Landscape
The study follows the research trajectory established at the Boston University Neurophotonics Center regarding non-invasive brain imaging. It represents a significant step in verifying portable technology against traditional clinical gold standards.
The validation of this wearable suggests a future where patients can monitor neurovascular health non-invasively at home. This could potentially reduce the need for constant clinical supervision for individuals requiring regular brain blood volume tracking.
The takeaway
Advancements in wearable sensors are bridging the gap between hospital-grade neuroimaging and accessible, daily health monitoring. Patients should continue to consult with medical professionals before relying on wearable data for clinical diagnosis.
