New preprint! Model connectivity: leveraging the power of encoding models to overcome the limitations of functional connectivity (Meschke et al., in review). Functional connectivity (FC) is the most popular method for recovering functional networks of brain areas with fMRI. However, because FC is defined as temporal correlations in brain activity, FC networks are inevitably confounded by noise and their function cannot be determined directly from FC. To overcome these limitations, we have developed model connectivity (MC). MC is defined as similarities in encoding model weights, which quantify reliable functional activity in terms of interpretable stimulus- or task-related features. In this paper we compare these two methods directly in a language comprehension dataset. We confirm the confounds of FC, and we show that MC does not suffer from these confounds. MC recovers more spatially localized networks and it reveals their functional assignment. MC is powerful tool for recovering the functional networks that support complex cognitive processes.
