- Final version (paywall), Preprint version, even older biorXiv preprint with different experimental dataset.
- Topology of network connectivity:
Ripple influence on small cortical site, 10 trials:
Blue - cortical spiking ahead of ripple. Black - cortical spiking after ripple. Red - schematically interposed ripple spikes.

on small cortical site (unpublished):
Up-state influence on hippocampal activity (little older model, unpublished):
Blue - CA3 spiking of ahead of delivering Up-state spiking. Black - CA3 spiking following Up-state spikes. Red - schematically interposed Up-state spikes.
Travelling Up-state wave influence on CA3 activity, 1 trial (unpublished).
Sharp-wave (and following ripple in CA1) tends to stay at similar time, likely on the spot of peaking subthreshold oscillation.
Highly synchronized Up-state influence on CA3 activity,1 trial (unpublished).
Increasing CX -> CA3 input (e.g. synchronizing DU transition) will trigger sharp wave in more causal fashion.
