摘要

In addition to information on localization of brain functions, data from fMRI experiments contain also cues about the functional connectivity among modular units. We propose a data-driven deterministic clustering algorithm based on temporal cross-correlations and elements of graph theory to detect functionally connected regions. The cluster concept can be changed in a controlled manner to reveal the functional connectivity structure in detail. The algorithm is applied to data from a motor task and shows to successfully determine clusters related to the stimulus. Furthermore, the method can be extended to include the analysis of temporal relations between different brain regions.
