note = {During different states of hippocampal network activity neurons receive excitatory synaptic input on dendritic compartments and transform it into axonal action potential output. The ensemble output of pyramidal neurons activates local inhibitory microcircuits, which provide recurrent compartment-specific inhibition. In the present study it was observed that neuronal activity patterns that are likely to be present during sharp-waves recruit recurrent inhibition differently than repetitive activity at theta frequency. The observed results suggest that this could adapt the efficacy of input-output conversion to the network-state. In the present study dendritic spikes and their activity-dependent plasticity were identified as specialized signals, which endow correlated excitatory branch input with the ability to withstand recurrent inhibition and to generate precisely timed action potential output independent of the previous activity. These findings suggest that dendritic spikes may provide a cellular correlate for reliable and temporally precise reactivation of behaviorally relevant neuronal assemblies during both exploration and sleep.},
