Resting-state functional connectivity MRI (rs-fcMRI) can be reliably performed in mice, producing high-resolution whole-brain images. The functional connections strongly align with the brain's structural wiring, as mapped by anterograde tracer studies. Large-scale network properties previously seen only in primates also exist in rodents, though with some differences. A potential default mode network (DMN)—a system important for social cognition and disrupted in many disorders—was identified in the mouse brain both structurally and functionally. These findings validate mouse rs-fcMRI as a translational bridge, allowing stronger links between cellular and molecular manipulations in mice and human brain conditions.
