I would suggest you read:
(1) Raichle et al. A default mode of brain function.
http://www.pnas.org/content/98/2/676.long
(2) Fox et al. The human brain is intrinsically organized into
dynamic, anticorrelated functional networks.
http://www.pnas.org/content/102/27/9673.long
(3) Smith et al. Correspondence of the brain’s functional architecture
during activation and rest. http://www.pnas.org/content/106/31/13040.full.pdf
Basically, the brain contains a number of different networks that have
been characterized at rest. The default-mode network is one of these
networks. If you put a seed in one of the regions in the network, it
will correlate with the other regions in the network at rest. During
task, the activity in these regions decrease, with a few exceptions.
It was named based on the 2001 paper from Raichle. If you seed other
regions outside the network you will get correlations with the other
networks.
