Studying the Spatial Distribution of Physiological Effects on BOLD Signals Using Ultrafast fMRI
The blood-oxygen-level dependent (BOLD) signal in functional MRI (fMRI) reflects both neuronal activations and global physiological fluctuations. These physiological fluctuations can be attributed to physiological low frequency oscillations (pLFOs), respiration, and cardiac pulsation. With typical T...
