Achieving high temporal resolution using a sliding-window approach for SPARKLING fMRI data: A simulation study

Résumé

In light of the mounting interest in temporal resolution in BOLD fMRI, we explore the sliding-window approach, specifically using the SPARKLING encoding scheme. A simulation study is conducted for 2D BOLD fMRI and demonstrates the possibility through the sliding window approach to detect oscillations beyond 0.2Hz in the BOLD response and separate the physiological noise from the neural activity by improving the temporal resolution.
