Challenging the notion of a task-negative network: default mode network involvement under varying levels of cognitive effort
Sarah Weber, André Aleman, Kenneth Hugdahl preprint
Abstract Everyday cognitive functioning is characterized by constant alternations between different modes of information processing, driven by fluctuations in environmental demands. At the neural level, this is realized through corresponding dynamic shifts in functional activation and network connectivity. A distinction is often made between the Default Mode Network (DMN) as a task-negative...
