“…Our work provides the first insight of PO neuronal firing during SWDs in a freely moving GAERS. Sorokin et al (2020) recorded from a mouse model of ASs and observed a ramp in PO firing preceding the onset, but this feature was variable and not observed here. However, overall firing rates were similar and alike Sorokin et al (2020), a reduction in firing, followed by a sharp increase was observed just prior to SWD onset.…”
