Comparing causality measures of fMRI data using PCA, CCA and vector autoregressive modelling.

Shah, Adnan; Khalid, Muhammad; Seghouane, Abd-Krim


Extracting the directional interaction between activated brain areas from functional magnetic resonance imaging (fMRI) time series measurements of their activity is a significant step in understanding the process of brain functions. In this paper, the directional interaction between fMRI time series characterizing the activity of two neuronal sites is quantified using two measures; one derived based on univariate autoregressive and autoregressive exogenous (AR/ARX) and other derived based on...[Show more]
