Physio-fUS: a tissue-motion based method for heart and breathing rate assessment in neurofunctional ultrasound imaging.

ABSTRACT:

Background

Recent studies have shown growing evidence that brain function is closely synchronised with global physiological parameters. Heart rate is linked to various cognitive processes and a strong correlation between neuronal activity and breathing has been demonstrated. These findings highlight the significance of monitoring these key physiological parameters during neuroimaging as they provide valuable insights into the overall brain function. Today, in neuroimaging, assessing these parameters requires additional cumbersome devices or implanted electrodes. Here we demonstrate that ultrasonic neurofunctional imaging data alone is sufficient to extract these parameters.

Methods

In this work, we performed ultrafast ultrasound imaging in male rodents and human neonates, an
