Figure 8. Parcellation-free spatial maps obtained using ICA.

Figure 8

(A) After applying an automatic model order selection and manually removing potential artifacts, 26 spatial components remained. (B) Activation levels derived from fMRI were set into a matrix of [150 subjects]×[202 time points]×[26 components]. Abbreviations: *, sampling time point, corresponding to the TR (here, 2638 ms); a.u., arbitrary units (of activation intensity). (C) Anatomical reference for IC pairs: each pair of ICs was assigned an arbitrary number, which is used as reference in the manuscript.
