Figure 1. Epoch of onset convulsive movement. This is a single epoch taken from the seizure of Animation 2. Traces are labeled corresponding to the ROIs for the head, right upper extremity, and left upper extremity.

Figure 2. Time relationships for the partial complex seizure of Animation 3. Note the initial shift in the Head trace, followed very shortly by the right upper extremity (RUE) and then left upper extremity (LUE) movements (Movement Coherence). The relaxation phase is seen near the end of the epoch.

Figure 3. Second episode, recorded as in Fig. 2. Note the virtual superimposability of the head-RUE-LUE with high a degree of coherence both for the onset (Head-RUE-LUE) complex initially and the relaxation phase toward the end of the epoch as compared to Figure 2. (There is a large artifact caused by a change in scene lighting near the middle of this epoch.)

Figure 4. Display of head adversion epoch shown in Animation 4. The ROI for this sequence is the blue overlay at the end of the pointer. The adversive movement is mainly smooth initially, but some evident clonic activity is seen toward the end. This is more evident as the circumoral myoclonus becomes dominant (Anim. 5, Fig. 5).

Figure 7. Three epochs taken from the seizure of Animation 7. (A) Onset of thrashing movement. (B) General thrashing has subsided, and head versive movement with development of mouthing movements can be seen in the Chin trace (as labeled). (C) Overall movement has decreased, and prominent activity is now oral, as shown in the Chin trace.
