Central Executive Network (CEN)

The central executive network (CEN) is a brain network involved in focused, goal-directed thinking — the kind of mental activity required for attention, problem-solving, planning, decision-making, and working memory. It becomes more active when we’re engaged in a task that requires effort and concentration, and less active when the mind is at rest. Key regions include the dorsolateral prefrontal cortex and posterior parietal cortex, which work together to support cognitive control (or executive function/EF) — the ability to hold information in mind, filter distractions, and guide behavior toward a goal.

The CEN functions in contrast to the default mode network (DMN), which supports internally directed thought. The salience network (SN) helps coordinate between the two — shifting the brain into a focused, task-oriented state when needed, or allowing a return to inward reflection. When the CEN is underactive or not well coordinated, it can show up as difficulty concentrating, disorganization, or trouble following through on tasks—patterns often seen in conditions such as ADHD, depression, and after chronic stress.
