Separating respiratory-variation-related fluctuations from neuronal-activity-related fluctuations in fMRI
RM Birn, JB Diamond, MA Smith, PA Bandettini - Neuroimage, 2006 - Elsevier
Subtle changes in a subject's breathing rate or depth, which occur naturally during rest at
low frequencies (< 0.1 Hz), have been shown to be significantly correlated with fMRI signal …
