Appendix 1—figure 10. Unusual Fold Limit Cycle seizures.

Each example is a single electrode from a separate patient, showing the voltage trace at the seizure focus. (A) Spike amplitude increases at end of seizure. (B) Abrupt start/stop of low voltage fast activity, without any change in frequency. (Note: the slow downward deflection was too slow to be labeled a DC shift). (C) Seizure with low voltage fast that progresses into arbitrary spike waves. Scale bars: 1 mV by 10 s.
