Why the study?
The roles of oxygen and carbon dioxide blood levels in neuronal activity and BOLD signal are complex and remain under investigation.
Key points are not available for this paper at this time.
Breathing patterns linked to anxiety/depression may mediate psychopathology-cognitive decline risk via BOLD effects; leaves open whether respiratory interventions alter dementia trajectories.
Neuronal brain activity is assumed to be reflected by blood level oxygenation levels, also known as BOLD signal, measured with fMRI. A scan of the literature points to both oxygen and carbon dioxide blood levels effects on BOLD fMRI. The roles of oxygen (O2 ; hypoxia/hypoxemia, hyperoxia) and carbon dioxide (CO2 ; hypocapnia, hypercapnia) in neuronal activity and BOLD signal are complex and still under investigation [1,2]. Inspiration while varying levels of O2 and CO2 in the air have been used to investigate resting state fMRI [3].
