The olfactory bulb theta rhythm follows all frequencies of diaphragmatic respiration in the freely behaving rat.

摘要: Sensory-motor relationships are part of the normal operation sensory systems. Sensing occurs in context active sensor movement, which turn influences processing. We address such a process rat olfactory system. Through recordings diaphragm electromyogram (EMG), we monitored motor output respiratory circuit involved sniffing behavior, simultaneously with local field potential (LFP) bulb (OB) rats moving freely familiar environment, where they display wide range frequencies. show that OB LFP represents sniff cycle high reliability at every frequency and can therefore be used to study neural representation drive cortex.
