Dorsal attention network

From Wikipedia, the free encyclopedia
Dorsal and ventral attention systems
Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation.[1]

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]

Anatomy

[edit]

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]

Function

[edit]

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]

Clinical significance

[edit]

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]

Nomenclature

[edit]

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]
