1/2 Cognition is expensive
The regions of the brain that are more connected or more active consume much more glucose, up to 67% more if we compare the frontoparietal networks (decision making, problem solving) with the sensory-motor areas.

That's a good insight, and we try to make the point that salience has a strong, facilitatory role in attention. We still think it's remarkable not to find *any* difference in the functional connectivity of dorsal attention network and frontoparietal network, the "classical" attention networks.

Attention and episodic memory interact closely:
* Goal-directed (top-down) attention helps prioritize relevant information.
* Stimulus-driven (bottom-up) attention responds to salient events.
We discuss how these systems shape memory encoding and retrieval. 2/N

James previously showed that you can decode the contents of visual working memory from the cerebellum akin to what you’d expect from frontoparietal areas. The cerebellum is clearly involved in many different cognitive processes, but its computational role remains unclear.
