Dorsal attention network
Encyclopedia
The dorsal attention network (DAN) is one of two sensory orienting systems in the human brain, the other being the ventral attention network
. It is involved in voluntary (top-down) orienting and shows activity increases after presentation of cues indicating where, when, or to what subjects should direct their attention. The dorsal attention network is bilateral and includes the intraparietal sulcus
and the junction of the precentral and superior frontal sulcus (frontal eye fields
) in each hemisphere.
Ventral attention network
The ventral attention network is one of two sensory orienting systems in the human brain, the other being the dorsal attention network. Its main function is to reorient attention towards salient stimuli. The VAN is considered to be involved mostly, if not entirely, in involuntary actions...

Intraparietal sulcus
The intraparietal sulcus is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion. The IPS contains a series of functionally distinct subregions that have been intensively investigated using both single cell neurophysiology in primates and human...
