Resting State Functional Connectivity in Brain Studied by fMRI Approach

Abstract

Abstract:

Resting state functional connectivity has been studied extensively by functional magnetic resonance imaging (fMRI) approach. Synchronic low frequency fluctuations in resting state fMRI data are analyzed by different methods to measure functional connectivity between different brain regions. The most studied resting state brain network is the default mode network which might subserve basic brain functions related to consciousness. In this paper, the fMRI approach to study resting state brain functional connectivity is reviewed. The data analysis methods and the characteristics of the resting state networks are summarized. The relationship between the resting state networks and anatomical connectivity defined by white matter tracts is discussed.

Key words: fMRI, functional connectivity, resting state
