This study develops a multi-channel SCOS system to map human cerebral blood flow changes during brain activation, showing spatial heterogeneity and validating its accuracy with a phantom.

This paper develops a high-speed Speckle Contrast Optical Spectroscopy (SCOS) system for cuffless blood pressure estimation, showing a 31% improvement over photoplethysmography (PPG) in systolic BP estimation with low error.

This study shows that aging in mice leads to reduced cortical spectral power and specific declines in functional connectivity in certain brain networks.
