     • Human brain imaging, for example, links both working memory and attention to a distributed cortical and subcortical “multiple demand” system—important in many aspects of behavioral control—with recent data indicating at least nine separate multiple-demand patches in frontal, parietal, and temporal cortex and associated activity in caudate, thalamus, and cerebellum. 9 In any particular task, activity in this nine-patch network must be linked to activity in multiple, more domain-specific regions...

   Why do cognitive brain states recur across different cognitive tasks?

   • This dynamic flow aligns with unique cognitive brain states that recur across distinct cognitive tasks. We next found that the flow of activity reflects an ‘integrative core’ that maximizes information processing complexity over relatively long timescales.

   How can complex brain networks be used to analyze brain function?

   • The analysis of complex brain networks can be used to interrogate the organizational properties of the brain that are crucial for its functional dynamics 1. Network accounts of brain function have hypothesized that a ‘dynamic core’ of regions flexibly guides the flow of activity in the brain to facilitate cognition 2.

   What is dynamic functional organization of the brain across cognitive tasks?

   • We found that the dynamic functional organization of the brain across a suite of cognitive tasks describes a flow along a low-dimensional state space. This dynamic flow aligns with unique cognitive brain states that recur across distinct cognitive tasks.

   Does resting-state functional network topology describe computational mapping between brain regions?

   • We developed a new approach—information transfer mapping—to test the hypothesis that resting-state functional network topology describes the computational mappings between brain regions that carry cognitive task information.

   How does brain activity affect cognitive function?

   • The human brain is a complex adaptive system in which a vast array of behaviors arises from coordinated neural activity across diverse spatial and temporal scales. Linking activity within this large-scale neural architecture to cognitive function remains an important goal for neuroscience.

   Is there a neural mechanism for multiple tasks?

   • It is clear that there is no single neural mechanism for multiple tasks. Instead, there are many potential neural mechanisms, depending on the collection of tasks, the method that a biological or artificial system uses to acquire the tasks, and (in the case of biological systems) the brain areas studied.

   However, the neural mechanism by which multiple tasks are accomplished within the same system is largely unclear. We start by discussing how different tasks can be related, and methods to generate large sets of inter-related tasks to study how neural networks and animals perform multiple tasks.
