Diagram representing the number of papers reviewed for the present work, subdivided on the basis of their goal, functional network studied, and analytical method used, reaching a total of 1452 patients examined [22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55]. The references are reported in order of citation. Certain studies explored different aspects; therefore, the sum of subgroups may be greater than the actual number of articles. MN: motor network; LN: language network; DMN: Default Mode Network; FPN: fronto-parietal network, SMN: sensorimotor network; ICA: independent component analysis; NN: Neural Network; FC: Functional Connectivity evaluation; GA: graph analysis.
