Frequency domains of resting state default mode network activity in schizophrenia

Psychiatry Res. 2013 Oct 30;214(1):80-2. doi: 10.1016/j.pscychresns.2013.05.013. Epub 2013 Aug 1.

Abstract

Probabilistic independent component analysis was applied to identify the default mode network (DMN) in resting state data obtained with functional magnetic resonance imaging from 25 DSM-IV schizophrenia and 25 matched healthy subjects. Power spectrum analysis showed a significant diagnosis × frequency interaction and higher power in one frequency band, indicating an alteration of DMN frequency spectrum in schizophrenia.
