"Hippocampal Respiration-Driven Rhythm Distinct from Theta Oscillations in Awake Mice"

This work demonstrates that the hippocampus of awake mice produces slow oscillations that are entrained by nasal respiration. The rhythm is close in frequency to, but distinct from, classical theta oscillations. The results suggest that respiration-coupled oscillations aid the exchange of information between olfactory and memory networks.
