Task-evoked brain functional magnetic susceptibility mapping by independent component analysis (Ï¿ICA)

⿢Complex division extracts temporal phase changes.⿢Brain functional Ͽ dataspace is reconstructed by CIMRI.⿢Both ICA and SPM could extract a task-evoked functional map from a 4D fMRI dataset.⿢ϿICA-extracted functional map reveals bidirectional Ͽ responses.⿢High-resolution fMRI data enables function-structure colocalization.
