A Signal-Processing-Based Approach to Time-Varying Graph Analysis for Dynamic Brain Network Identification

Figure 1

Event interval detection: 6 event intervals are identified which roughly correspond to the stimulus processing (−1000 to −102 ms), pre-ERN (−101 to 0 ms), ERN (1 to 117 ms), post-ERN (118 to 259 ms), Pe (260 to 461 ms), and intertrial (462 to 1000 ms) intervals, respectively. The subjects respond to the stimulus at time 0 ms where the response is represented by the red spike.
