    Notes: Summary Unit discharges associated with ultrasonic vocalization were recorded from the rat medullary region including the nucleus ambiguous (NA). Three types of units were distinguished: ultrasound-related (US), expiration (EXP) and inspiration (INSP) units. Both US and EXP units discharged with tonic bursts mostly prior to ultrasounds. US units were silent during respiration while EXP units discharged synchronously with expiration. During ultrasonic vocalization INSP units suppressed their discharges which were otherwise synchronized with inspiration. Histological examination revealed that US and EXP units were recorded from the ventral division of the NA and the adjacent medullary region where the NA contained large cells and the adjacent region consisted of small cells. These results suggest that both US and EXP units are NA motoneurons responsible for ultrasound emission. EXP units were always supplied with respiratory afferents while US units were not.

    A twin optically-pumped far-infrared CH3OH laser for plasma diagnostics (1980)

    Notes: Abstract A twin optically-pumped far-infrared CH3OH laser has been constructed for use in plasma diagnostics. The antisymmetric doublet due to the Raman-type resonant two-photon transition is reproducibly observed at 118.8 μm. With the 118.8-μm line, it is obtained from the frequency separation of the anti-symmetric doublet that CH3OH absorption line center is 16±1 MHz higher than the pump 9.7-μm P(36) CO2 laser line center. It is shown that the Raman-type resonant two-photon transition is useful in order to get several-MHz phase modulation for the far-infrared laser interferometer. Some preliminary performances of this twin laser for the modulated interferometer are described.
