WebDec 1, 2024 · Resting-state fMRI (rs-fMRI) is a widely used neuroimaging tool that measures spontaneous fluctuations in neural blood oxygen-level dependent (BOLD) signal across the whole brain, in the absence of any controlled experimental paradigm. WebFeb 15, 2024 · A large number of fMRI studies have shown that the temporal dynamics of evoked BOLD responses can be highly heterogeneous. Failing to model heterogeneous responses in statistical analysis can lead to significant errors in signal detection and characterization and alter the neurobiological interpretation.
