A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

Laser speckle contrast imaging (LSCI) measures blood flow across wide areas of brain tissue with high precision, providing new evidence of how blood vessels coordinate brain perfusion. Temporal ...

Researchers developed a wearable device that can be used for non-invasive stroke risk assessment. The device uses speckle contrast optical spectroscopy to track changes in blood flow and volume in the ...
