In neuroscience, the default network is a network of brain regions that are active when the individual is not focused on the outside world and the brain is at wakeful rest. Also called the default mode network (DMN), default state network, or task-negative network (TNN), it is characterized by coherent neuronal oscillations at a rate lower than 0.1 Hz (one every ten seconds). During goal-oriented activity, the DMN is deactivated and another network, the task-positive network (TPN) is activated. The default network may correspond to task-independent introspection, or self-referential thought, while the TPN corresponds to action, and that perhaps the TNN and TPN may be "considered elements of a single default network with anti-correlated components".
Famous quotes containing the words default and/or network:
“In default of inexhaustible happiness, eternal suffering would at least give us a destiny. But we do not even have that consolation, and our worst agonies come to an end one day.”
—Albert Camus (1913–1960)
“Parents need all the help they can get. The strongest as well as the most fragile family requires a vital network of social supports.”
