The paper quantifies co-occurrence of ripples with theta oscillations across hippocampal strata in foraging rats, finding theta ripples occur in ~20% of ripple events and show theta-phase preferences.

This study shows that sharp place-field tuning in hippocampal neurons emerges despite structural and biophysical variability through mechanisms like synaptic democracy and ion-channel degeneracy.

The paper shows that sharp place cell responses can arise from randomly dispersed iso-feature synapses, relying on dendritic channels and NMDA receptors, challenging previous assumptions about synaptic clustering.
