Dorsal attention network

The core regions of the DAN are the IPS and FEF of each hemisphere. Other regions of the network may include the middle temporal region (MT+), and ventral premotor cortex. Less studied regions include the right dorsolateral prefrontal cortex and superior colliculus. == Function ==

The DAN is most prominently involved in goal-directed, voluntary control of visuospatial attention. suggest that the network is involved in general top-down selection of stimuli and responses, including other modalities (e.g. auditory, tactile). However, evidence that the full DAN is involved in auditory top-down attention has been questioned, as tests that make said claims incorporated both auditory and visual stimuli. The dorsal attention network dynamically interacts with the ventral attention network (or salience network) according to task demands. == Clinical significance ==

Reduced connectivity within the dorsal and ventral attention networks has been linked to higher levels of attention deficit hyperactivity disorder symptoms. Similarly, reduced connectivity between the DAN and the frontoparietal network is associated with major depressive disorder. On the other hand, overactivation of the DAN has been observed in patients with schizophrenia. == Nomenclature ==

There are several variations of this network's name in neuroscience literature, such as the dorsal attention system, Until the discovery of other networks, such as the frontoparietal control network, the term task-positive network referred to the DAN. The term task-positive networks is still sometimes used to refer to all non-default-mode networks. In 2019, Uddin et al. proposed that dorsal frontoparietal network (D-FPN) be used as a standard anatomical name for this network. == References ==
