The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye fields (FEF). [2] [3] It is named and most known for its role in voluntary orienting of visuospatial attention. [4] [5]
As the IPS and FEF were noticed to be activated during many attention-demanding tasks, this network was sometimes referred to as the task-positive network to contrast it against the task-negative network, or default mode network. [6] However, this dichotomy is now considered misleading, because the default mode network can be active in certain cognitive tasks. [7]
The core regions of the DAN are the IPS and FEF of each hemisphere. [8] Other regions of the network may include the middle temporal region (MT+), [6] superior parietal lobule (SPL), supplementary eye field (SEF), [9] and ventral premotor cortex. [10]
More recent works indicate that the cerebellum may participate in this network as well. [11] [12] Less studied regions include the right dorsolateral prefrontal cortex and superior colliculus. [10]
The DAN is most prominently involved in goal-directed, voluntary control of visuospatial attention. [4] [5] Corbetta et al., who first defined and named the DAN in the early-to-mid 2000s, [5] [13] suggest that the network is involved in general top-down selection of stimuli and responses, including other modalities (e.g. auditory, tactile). [14] 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. [15]
The dorsal attention network dynamically interacts with the ventral attention network (or salience network) according to task demands. [1] The inferior frontal junction configures this interaction between the two networks during task switches or attention shifts. [16]
Reduced connectivity within the dorsal and ventral attention networks has been linked to higher levels of attention deficit hyperactivity disorder symptoms. [17] [18] Similarly, reduced connectivity between the DAN and the frontoparietal network is associated with major depressive disorder. [19] On the other hand, overactivation of the DAN has been observed in patients with schizophrenia. [20]
There are several variations of this network's name in neuroscience literature, such as the dorsal attention system, [1] dorsal frontoparietal attention network, [9] and frontoparietal attention network. [21] Until the discovery of other networks, such as the frontoparietal control network, the term task-positive network referred to the DAN. [22] The term task-positive networks is still sometimes used to refer to all non- default-mode networks. [23]
In 2019, Uddin et al. proposed that dorsal frontoparietal network (D-FPN) be used as a standard anatomical name for this network. [10]
