Abstract

We exploit directed information to examine the causal relationship between EEG data in response to audio stimulus. Specifically, we conduct experiments wherein the EEG activity of subjects is recorded as they listen to audio with time- varying audio quality between two different levels. Different types of directed information measures are then used to quantify the information flow between EEG sensors, which are grouped into different regions of interest over the cortex. Further, we determine the analytical relationship between these different directional measures and compare how well they are able to distinguish between the perceived audio quality.
