Stimulus Set Meaningfulness and Neurophysiological Differentiation: A Functional Magnetic Resonance Imaging Study
Integrated information Φ* results for the movie, scrambled movie, and ‘TV noise’ conditions. Colors of bars represent conditions (dark gray: movie, medium gray: scrambled movie, light gray: TV noise). Upper left panel: the group-mean of Φ* calculated by using time lag of 4 second and ROI set 1. Error bar represents standard error of the mean for each measure in each condition. Asterisks indicate significant differences of the group means (p<0.05, corrected). Upper right panel: the group-mean of Φ* calculated by using time lag of 4 second and ROI set 2. Lower panel: Φ* calculated in our representative subject with ROI set 1, showing robust results across different time lags (1–10 seconds). In this panel, error bar indicates standard deviation of the mean for 1000 sets of 80 ROIs (see Methods).
