我们重新审视最近的证据，表明鼻呼吸在啮齿动物大脑的几个区域中产生与呼吸相同频率的振荡。此外，呼吸调节特定伽玛子带（70-120Hz）的幅度，在额叶区域最为显着。由于啮齿类动物经常以 δ 和 θ 频率呼吸，我们警告说，先前对 δ 和 θ 功率及其跨区域同步性以及 δ-γ 和 θ-γ 耦合的研究可能已经检测到呼吸引起的节律和呼吸-γ 耦合。我们认为，同时跟踪呼吸和电生理记录对于正确识别大脑振荡是必要的。我们假设呼吸引起的振荡有助于大脑中的远程通信。
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 modulates the amplitude of a specific gamma sub-band (70–120Hz), most prominently in frontal regions. Since rodents often breathe at delta and theta frequencies, we caution that previous studies on delta and theta power and their cross-regional synchrony, as well as on delta–gamma and theta–gamma coupling, may have detected the respiration-entrained rhythm and respiration–gamma coupling. We argue that the simultaneous tracking of respiration along with electrophysiological recordings is necessary to properly identify brain oscillations. We hypothesize that respiration-entrained oscillations aid long-range communication in the brain.
