Determination of information flow direction among brain structures by a modified directed transfer function (dDTF) method

J Neurosci Methods. 2003 May 30;125(1-2):195-207. doi: 10.1016/s0165-0270(03)00052-9.


A modification of directed transfer function-direct DTF-is proposed for the analysis of direct information transfer among brain structures on the basis of local field potentials (LFP). Comparison of results obtained by the analysis of simulated and experimental data with a new dDTF and DTF method is shown. A new measure to estimate direct causal relations between signals is defined. The present results demonstrate the effectiveness of the new dDTF method and indicate that the dDTF method can be used to obtain the reliable patterns of connections between various brain structures.
