Figure 3. Segmentation of the seizure early propagation period reveals successive MUA dynamics in all patients.

Figure 3

MUA-based segmentation during seizure early propagation, similar to Fig. 2C, applied to 1 seizure in each of the 5 patients (top and bottom traces: respectively LFPs and high-pass MUA from same electrode; heat map: MUA rate across electrodes). The first 4 patients had spike-and-wave seizures, while the last patient (P5) had gamma seizures. Note that the maximum in MUA rate occurs within a single stage in two patients (P1 and P4) but is distributed across several distinct stages in two other patients (P2 and P3). In the patient with gamma seizures (P5), no peak in MUA rate is apparent but a structure composed of discrete stages can still be identified. Overall, a succession of discrete stages each characterized by its own MUA dynamics is observed in all patients/seizures, but this structure is not the same across patients.
