According to our new study, there exists a extracerebrovascular reactivity induced by changes in breathing -> sciencedirect.com/science/articl… Both hypocapnia & hypercapnia exert a significant impact on not only CBF but also on extracerebral tissue hemodynamics. Relevant for #fNIRS

Best practices for simultaneous measurement of NIRS-based cerebral and muscle oximetry during exercise -> sciencedirect.com/science/articl… NIRS-based oximetry i) is a valuable tool for exercise physiology & 2) measurements are influenced by the device used & must be interpreted carefully

The somatic mutation theory of cancer (i.e. the prevailing paradigm that tumorigenesis is caused by cancer-driving somatic mutations & clonal expansion) is most likely incorrect. Great new paper about this insight: journals.plos.org/plosbiology/ar…
