Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on perfused tissue, the detected speckles, or "grains" ...

Engineers at the University of California San Diego have developed a wearable ultrasound patch that can offer continuous, non-invasive monitoring of blood flow in the brain. The soft and stretchy ...

LSCI emphasizes large surface veins and heartbeat-locked speckle changes (top raw); IPPG emphasizes tissue pulsations (bottom raw). Beat-normalized time courses from both methods co-evolve, revealing ...

Enhancing prefrontal cortex (PFC) cognitive functions requires identifying suitable exercises that increase cerebral blood flow. A recent study using functional near-infrared spectroscopy found that ...

Deepinder Goyal-backed Temple is an experimental brain wearable that could cost around Rs 72,000. Here's what it does, how it works, and why it remains a research-focused device.
