The task-positive network (TPN), also known as the dorsal attention network (DAN), is one of two sensory orienting systems in the human brain, the other being the task-negative 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.
During rest the TPN has been claimed to subserve intermittent “external awareness”, defined as the conscious perception through different sensory modalities of one`s surrounding environment.
