The discharge of neurons in the nucleus parabrachialis medialis (NPBM) was examined for the presence of high-frequency oscillations (HFOs) by autocorrelation analysis. HFOs were not observed in NPBM activity during any sleep-waking state. In contrast, HFOs were found in the activity of medullary respiratory neurons. It is concluded that the NPBM is not the source of HFOs in the respiratory system.
