Information analysis of EEG recordings during vision of naturalistic movies. The Figure shows EEG responses, and their information, recorded from a human subject watching 5 s-long repeated presentations of a color movie. Data from Panels (A-D) were taken from an example electrode (whose location is reported by the arrow in Panels E-F). A: The time course of the phase of the delta-band (0.1 – 4 Hz) EEG during a single trial (i.e., a single movie presentation). The single-trial delta-band EEG has been color-coded according to its phase-angle binned into four equally spaced intervals between -π and π. B: The same single-trial delta-band EEG from the example electrode was color-coded according to the instantaneous power binned into four equally probable intervals. C: Time course of the instantaneous phases of the 0.1 – 4 Hz (delta) EEG from the example electrode over 30 repetitions of the movie. Phase values were color coded into quadrants exactly as illustrated in Panel (A). D: Time course of the binned instantaneous power of the 0.1 – 4 Hz (delta) EEG from the example electrode over 30 repetitions of the movie. Power values were color coded into quadrants exactly as illustrated in Panel (B). E: The information conveyed by the binned phase in the delta (0 – 4 Hz), theta (4 – 8 Hz), alpha (8 – 15 Hz) and beta (15 – 30 Hz) frequency bands is plotted topographically across the electrode locations. F: The same topographic plot for the EEG instantaneous power information.
