Abstract in brief

This article introduces a novel method called blind deconvolution to better analyze brain connectivity from resting state fMRI data, addressing limitations of previous techniques like Granger causality.
Because resting state data lack explicit external inputs, the method identifies spontaneous neural events by detecting significant BOLD signal peaks and estimates region-specific hemodynamic response functions (HRFs) to improve the interpretation of neural activity.
To manage computational challenges and redundancy in short, noisy datasets, the approach uses partial conditioning on a select set of brain regions, making the analysis more accurate and feasible.
