Supplementary Figure 11: Single-cell summaries for juxtacellular recording and labeling in vivo.

For all panels, morphology recovered from the recorded cell is pictured on top. The SW-triggered activity where a single sweep is shown on top (black), middle panel shows the SW-triggered raster where singe-spikes are black ticks and the first spike in a burst is indicated by a red tick and subsequent spikes in the burst are grey. a, and b are two additional examples of PCP4 negative thorny cells which predominantly fired single spikes during the SW (n = 2 cells). C and D are two additional examples of athorny neurons where bursting can be observed prior to the onset of the SW (n = 3 cells). e-h are additional examples of thorny cells across different sub-regions of CA3, indicating consistent behavior during sharp-waves (n = 6 cells). i and j are two examples of CA2 neurons (+ PCP4) which had similar firing phenotypes to thorny CA3 pyramidal cells for comparison (n = 2 cells). k and l are CA1 cells as a further comparison, which only exhibited sparse firing within the SW LFP envelope (n = 2 cells). Note only athorny CA3 neurons exhibit a prominent burst-firing pattern prior to the onset of the sharp-wave.
