Surveilling microglia may favor lower tissue susceptibility to SD, while primed microglia could support SD occurrence. We propose that resting microglia balance out neuronal overactivation and make SD occurrence less likely. Once SD occurs, the homeostasis of the nervous tissue is challenged, microglia transform to a primed state, which together preserve or increase the susceptibility of the nervous tissue to sustain subsequent SDs.
