Executive control network
What is the Executive Control Network?
The executive control network (ECN) is a large-scale brain network centered on the dorsolateral prefrontal cortex and posterior parietal cortex that supports working memory, attentional control, and goal-directed behavior.
How it works
The ECN is studied through task activity and correlations between brain regions. The salience network and default mode network interact with it in models of cognitive control. The networks do not operate as a simple on/off switch: their relationships change with the task and context. Research on executive dysfunction examines altered network patterns, but such patterns are not standalone diagnoses.
Applied example
Imagine a task in which a red circle means press the left button and a blue circle means press the right button. You must keep that rule available while the colors change. Halfway through, the instructions reverse the mapping: red now means right and blue means left. You must update the rule and avoid responding according to the old one.
Researchers could compare activity while a rule is stable, immediately after it changes, and during rest. They could also measure errors and response times. This hypothetical task makes the control demands concrete; it does not establish which network pattern would appear without collecting and analyzing the data.
Why it matters
Keeping a goal in mind, ignoring distractions and adjusting your actions requires coordination across brain regions. The ECN gives researchers a way to study that coordination. It is more useful to think in terms of interacting networks than a single task-management center.
Seeley and colleagues identified correlated networks; Menon used network research to propose a model of their interactions.
