What is Dorsal Attention Network?
The Dorsal Attention Network (DAN) is a network of brain regions that support voluntary, goal-directed attention — "top-down" control of what we focus on, as opposed to "bottom-up" capture by salient stimuli.
Key Regions
- •Intraparietal sulcus
- •Frontal eye fields
- •Superior parietal lobule
Function
The DAN directs attention to task-relevant stimuli and suppresses irrelevant ones. It works in opposition to the Default Mode Network — when DAN is active, DMN tends to be suppressed.
Why does the dorsal attention network matter?
The dorsal attention network matters because it lets you hold attention on a goal even when other things compete for it. It helps keep a location, object, or feature "in mind" as a target, and it is closely tied to planning where the eyes will move next. This makes it central to everyday tasks like reading, searching a crowded scene, or driving.
It does not work alone. A second system, the ventral attention network, centered on the right temporoparietal junction and inferior frontal cortex, responds when something unexpected but important appears and can interrupt the current focus. Healthy attention depends on the balance between these two systems.
What happens when the dorsal attention network goes wrong?
When the dorsal attention network is disrupted, people have trouble directing and sustaining focus on purpose. The clearest example is spatial neglect after a stroke, usually on the right side of the brain, where a person ignores one side of space. Research suggests that neglect involves an imbalance between left and right dorsal attention regions, not only local tissue damage.
Altered activity in this network has also been reported in ADHD and some other conditions, but findings vary between studies, and the evidence does not yet support using it as a diagnostic marker.
In ONDA Life
Part 8 activates the "network of voluntary, directed attention." Training the DAN enables the shift from reactive attention (chaotic) to voluntary attention (controlled) — the heart of "I Focus."
