Intranetwork alteration in functional activity at rest based on current articles reviewed. Within‐network alteration in functional connectivity in bipolar disorder based on the triple network model. For each network, the key regions that belong to the network are shown in colored nodes. The size of the nodes represents hyperconnectivity, hypoconnectivity, or statistically similar (neurotypical) functional connectivity between the respective region and its nearby subregional structures, such as the functional connectivity between the dorsal and ventral part of the region, as compared to the healthy control group. The functional connectivity between regions are shown in edges, where the type of edge represents either hyperconnectivity, hypoconnectivity or statistically similar (neurotypical) functional connectivity as compared to the healthy control group.
