Respiration-entrained brain rhythms are global but often overlooked
We revisit recent evidence showing that nasal respiration entrains oscillations at the same
frequency as breathing in several regions of the rodent brain. Moreover, respiration …

Neocortical synaptic engrams for remote contextual memories
While initial encoding of contextual memories involves the strengthening of hippocampal
circuits, these memories progressively mature to stabilized forms in neocortex and become …
