Human hippocampal connectivity is stronger in olfaction than other sensory systems
During mammalian evolution, primate neocortex expanded, shifting hippocampal functional
networks away from primary sensory cortices, towards association cortices. Reflecting this …

Temporal relations between cortical network oscillations and breathing frequency during REM sleep
Nasal breathing generates a rhythmic signal which entrains cortical network oscillations in
widespread brain regions on a cycle-to-cycle time scale. It is unknown, however, how …
