Deepinder Goyal Reveals Temple BrainFlow Monitors Brain Blood Flow, Not Just Scalp
- •Deepinder Goyal announced a new validation study for Temple BrainFlow, a wearable blood-flow monitoring technology.
- •The study, published on bioRxiv and submitted for peer review, compared BrainFlow with time-domain NIRS (TD-NIRS) in 60 participants.
- •Participants underwent three physiological challenges: head-down tilt, stand-to-squat, and stand-to-supine.
- •BrainFlow showed strong correlations (0.84 to 0.91) with brain blood volume changes, significantly higher than with scalp blood volume (0.49 to 0.77).
- •The findings suggest BrainFlow captures signals more closely associated with brain blood volume, though it doesn't directly measure cerebral blood flow.
Key Questions Answered
Temple's second validation study compared the BrainFlow wearable with time-domain near-infrared spectroscopy (TD-NIRS) across 60 participants undergoing three physiological challenges: head-down tilt, stand-to-squat, and stand-to-supine.
The study showed that BrainFlow measurements had stronger correlations with brain blood volume, ranging from 0.84 to 0.91, compared to correlations of 0.49 to 0.77 with scalp blood volume across the tested physiological challenges.
Temple's first validation study evaluated the wearable's Brain Flow index against transcranial Doppler (TCD) ultrasound during exercise and postural transitions, involving healthy adult participants to track cerebral circulation changes.
