Networks associated with transient spontaneous BOLD events

Label	Cortical regions	Associated function
n1	Precentral, postcentral, and central gyrus, medial frontal cortex (SMA)	Sensorimotor (MN)a
n2	Striate cortex, occipital gyri (extrastriate cortex), cuneus	Visual (VN)b
n3	Posterior cingulate, precuneus, medial frontal cortex, inferior parietal cortex (supramarginal, angular gyri)	Episodic memory, self‐referential processing, default‐mode network (DMN)c
n4	Superior parietal lobule, intraparietal sulcus, postcentral, precentral/superior frontal gyrus, posteromedial parietal cortex (cingulate gyrus, paracentral lobule)	Working memory, dorsal attention network (DAN), “task‐positive” network, imagery.d

Classification of spontaneous BOLD events to known functional networks. Middle column shows the cortical regions corresponding to the spatial pattern of an event. Right column shows the associated function based on the similarity of the spatial pattern to known functional networks reported in the literature (footnotes). The functional networks identified were labelled n1–n4 (left column).
