From: Creative music therapy in preterm infants effects cerebrovascular oxygenation and perfusion

Group-averages of CMT-induced changes in cerebral tissue oxygenation and metabolism as well as systemic physiological signals, depending on the two subgroups. StO2: cerebrovascular oxygenation, FTOE: dependent fractional tissue oxygen extraction, SpO2: peripheral arterial oxygenation, PR: pulse rate. The optodes of the NIRS-based tissue oximeter were placed over the right prefrontal cortex and left auditory cortex.
