Exploration of functional connectivity in patients with brain tumors with Resting state functional MRI (rsfMRI) is expanding, but methodology used and results in previous studies are heterogenous. We explored the disruption of the functional connectivity of the Default Mode, Dorsal Attention and Fronto-Parietal Networks in 35 glioma patients, with a standardized method, using both Seed-Based Connectivity Analysis and Independent Component Analysis. The Default Mode was the most affected network, with global increased connectivity contrasting with a decreased connectivity in the corpus callosum. No difference in connectivity was found between IDH mutant or wildtype tumors.
