Resting state default mode network can be reliably traced using
fMRI. The integrity of the network has functional consequences.
9 healthy subjects performed non-trivial sequencing task during
fMRI. Deactivation during the active paradigm revealed the
default mode network. Nodes of this network play a role in the
neurobiology of schizophrenia. Therefore the method is usefull
for the schizophrenia research.
