Olfactory Bulb Field Potentials and Respiration in Sleep-Wake States of Mice

Figure 6

Representative examples of coherences between plethysmography (PG), thermocouple (TC), and olfactory bulb (OB) local field potentials (LFP) reveal clear peaks and their harmonics in waking but only between PG and OB in NREM and REM sleep (see also text for conclusions on OB LFP as source of respiration during sleep). PSD PG: power spectral density of the plethysmography signal.
