Resting-state FC has long been a source of debate. Recent evidence suggests that task-like patterns dominate its signal. To study less dominant components, we introduced a caricaturing method to project the data to a subspace orthogonal to these patterns. rdcu.be/eN1gJ

There is still much to learn about caricatured FC, but we conclude that dominant task-like patterns are not the only useful signals. What the caricatured data represents and how it can be optimized for downstream applications are exciting questions ready for future exploration.
