Abstract：
:In mature rats, electrical stimulation of the retrotrapezoid nucleus increased the amplitude and frequency of the high-frequency peak in the firing spectrum of the phrenic nerve, while the amplitude of medium-frequency peak and the amplitude ratio of medium- to high-frequency peaks decreased. These changes in spectral parameters were associated with accelerated increase in central inspiratory activity, decreased amplitude of phrenic nerve firing, and increased frequency of respiratory rhythm. It is hypothesized that being a relay structure of central chemosensitive mechanism, the retrotrapezoid nucleus regulates parameters of medium- and high-frequency spectral peaks of efferent electrical activity in the respiratory center together with the dorsal and ventral respiratory groups.
