Figure 2.

This figure depicts the process of creating epochs of EEG data corresponding to the behavioral microcoding. The file begins as continuous EEG with parent data on top and child on the bottom. Event codes are added to the EEG and separated into 1-second epochs corresponding to behavioral state (solid lines). A 500ms transition period (dotted line) is excluded as well as the extra time that does not fit cleanly into 1-second epochs. Epochs with remaining artifacts are then rejected, leaving only artifact-free epochs.
