Chapter 6 endnote 17, from How Emotions are Made: The Secret Life of the Brain by Lisa Feldman Barrett.
Some context is:

This tinkering [by the control network] ultimately helps your brain simultaneously to regulate your body budget, produce a stable perception, and launch an action. [...] In psychology, we have many names for describing this “tinkering,” such as keeping a goal in mind, focusing attention, weeding out distractions, selecting the best action, and so on, and we refer to them as different processes, such as working memory, selective attention, and so on.

There are many different scientific theories of control. Several review articles are a helpful introduction.[1][2][3][4][5][6][7][8]

To summarize, "control" means:

  • Keeping a goal in mind; called selective attention or working memory; ensuring that neural activity is maintained for the most task-relevant representation (i.e., the one with the best match to the situation, based on past experience, which is also referred to as the representation with the highest prior probability). To a neuron, “attention” means influencing its firing pattern.
  • Focusing on signal and ignoring noise; modulating the firing of some populations of neurons to keep information accessible and active to influence processing elsewhere in the brain. Less task-relevant representations are inhibited or are allowed to degrade.[9]
  • Selecting the best response and sending this information to the motor network so that the actions directed by the representation that best fits both past experience and the situation at hand (i.e., with the highest posterior probability) controls behavior. Control means minimizing conflict between different possible courses of actions, and tries to ensure that you can respond flexibly as the situation changes.

For many years, scientists assumed that a different region of the brain performed each of these abilities, but decades of brain research, including careful experiments and meta-analyses, have shown that the control network performs all of these functions.[10][11][12][10]

Sometimes reduced control can be a good thing.[13]

  9. The interoceptive network has an extra, special way of directing sensory sampling to eliminate prediction error: it can prevent sensory input from ever making it to cortex to begin with. (body-budgeting regions can gate thalamic reticular nucleus which inhibits sensory inputs to the cortex. For example, Zikopoulos, Basilis, and Helen Barbas. 2006.
