Abstract

A directional information flow technique is applied to investigate interactions among different parts of the brain during a conditioning paradigm using visually masked stimuli. Data of three phases, preconditioning, conditioning, and postconditioning for 17 subjects were analysed. The number of points above the mean+3 standard deviations of information flow profiles were used in a MANOVA analysis for comparing information flows in the three experimental phases. Significant differences in information flow were found between the P3 and P4 electrode pair while no such differences were found for the Oz and Cz electrode pair. Significant directional difference between P3 and P4 electrode pair does not exist
