Figure 1
Stimuli and behavior.
(A) Examples of REG and RAND scenes. The plots represent ‘auditory’ spectrograms, equally spaced on a scale of ERB-rate (Moore and Glasberg, 1983). Channels are smoothed to obtain a temporal …
Figure 2
RMS time-course of the scene-evoked response showing the main effect of scene temporal structure (REG versus RAND).
Thick horizontal green lines indicate time points for which there were significant differences between REG and RAND conditions (p<0.05 FWE corrected at the cluster level; Thin light-green lines show …

Appearance-evoked response.
(A) RMS time-course of the appearance-evoked response showing the main effect of scene temporal structure (REG versus RAND). Thick horizontal green lines indicate time points for which there were …

MEG time-course averaged over selected sensors responsive to the appearance-evoked M50 component.
(A) MEG from sensors showing positive signal at the time of the appearance-evoked M50 component. Thick horizontal green lines indicate time points for which there were significant differences in MEG …

Source reconstruction.
(A) Main effect of scene temporal structure at the time of the sustained portion of the scene-evoked response (500–800 ms post scene onset). Statistical map is overlaid onto an MNI space template …
