The intrinsic connectional architecture of functional networks (FN) in the mouse brain remains a significantly underexplored research area. The primary goal of our study is to systematically and comparatively probe using resting state fMRI (rsfMRI) the intrinsic brain functional connectivity of two mouse strains, intensively used in the fundamental and preclinical neuroscience: the C57Bl6/N and the Balbc/J strain. Using Independent Component Analysis (ICA), partial correlation and graph theory, we identify the relevant, influential nodes in each strain and show inter-strain differences in the large scale organization of FN.
