Supplementary Materials

The PDF file includes:

  • Fig. S1. Some, but not all, CA1 neurons emit SW-locked spikes.
  • Fig. S2. Spontaneous calcium transients are recorded simultaneously from multiple spines in a single neuron in a SW-emitting slice.
  • Fig. S3. SW participants receive spatially clustered spine activity during SWs.
  • Fig. S4. Sequential spine activity appeared more frequently than the chance level in SW participants.
  • Fig. S5. Temporal properties of sequential spine activity.
  • Fig. S6. Spines are recruited in sequences independent of their calcium activity frequency.
  • Fig. S7. Sequential spine activity is spatially clustered irrespective of the occurrence of SWs.
  • Fig. S8. Spines involved in sequence are localized in specific dendritic branches.
  • Fig. S9. Directionality of local sequences: Nonparametric analysis.
  • Fig. S10. Sequential spine activity induces larger calcium transients in nearby dendritic shafts.
