Overlapping networks

Chapter 4 endnote 27, from How Emotions are Made: The Secret Life of the Brain by Lisa Feldman Barrett.
Some context is:

Every other intrinsic network in the brain overlaps with the interoceptive network in at least one of its regions.[1] So the interoceptive network doesn’t create all of its predictions by itself.

The interoceptive network doesn’t create all of its predictions by itself. Interoception is closely tied to the two other intrinsic networks I listed briefly at the beginning of the chapter: the multimodal integration network[2] and the control network (also known as the frontoparietal control network[3] or the executive function network[4]). All three overlap with the interoceptive network, so they contribute to interoceptive predictions. (In fact, the frontoparietal control network and part of the interoceptive network — usually called the salience network — along with a third network called the dorsal attention network,[5] is sometimes called the multiple demand network[6] or the task positive network[7].)[8] Are you confused yet? Remember, scientists name networks in line with their own interests and experiments.

The multimodal integration network, which integrates prediction error in vision, hearing, touch, and interoception, adjusts interoceptive predictions based on the state of the outside world. The multimodal integration network overlaps with the interoception network the a set of regions, some of which include:

  • The anterior insula, tucked under the frontal and temporal lobes on the lateral surface of the brain
  • The ventrolateral prefrontal cortex (just above the anterior insula), also called Broca's Area
  • The anterior mid cingulate cortex on the medial surface of the brain, also called dorsal anterior cingulate cortex
  • The supplementary motor cortex just dorsal to the mid cingulate cortex

The control network is an optimizer that helps the brain make choices that keep your energy budget balanced. It helps to focus the brain’s attention and select between conflicting predictions. The control and interoceptive networks overlap at the anterior insula and at the mid cingulate cortex.
