    Notes: Summary In the decerebrate cat, recordings were made from neurons in the caudal medullary raphe nuclei to determine if they responded to electrical stimulation of the vestibular nerve and thus might participate in vestibulo-sympathetic reflexes. Many of these cells projected to the upper thoracic spinal cord. The majority (20/28) of raphespinal neurons with conduction velocities between 1 and 4 m/s received vestibular inputs; 13 of the 20 were inhibited, and 7 were excited. Since many raphespinal neurons with similar slow conduction velocities are involved in the control of sympathetic outflow, as well as in other functions, these cells could potentially relay vestibular signals to sympathetic preganglionic neurons. The onset latency of the vestibular effects was long (median of 15 ms), indicating the inputs were polysynaptic. In addition, 34 of 42 raphespinal neurons with more rapid conduction velocities (6–78 m/s) also received long-latency (median of 10 ms) labyrinthine inputs; 26 were excited and 8 were inhibited. Although little is known about these rapidlyconducting cells, they do not appear to be involved in autonomic control, suggesting that the function of vestibular inputs to raphe neurons is not limited to production of vestibulosympathetic reflexes. One hypothesis is that raphe neurons are also involved in modulating the gain of vestibulocollic and vestibulospinal reflexes; this possibility remains to be tested.

    Horizontal canal input to upper cervical commissural neurons (1993)
    Springer
    Experimental brain research 92 (1993), S. 549-552

    ISSN: 1432-1106

    Notes: Summary We studied in decerebrate, paralyzed cats, the effect of sinusoidal yaw rotation on upper cervical commissural neurons. The activity of some neurons was modulated by this stimulus, and they were classified as receiving input from the horizontal semicircular canal. The responses, which were mainly type II, were well correlated with the velocity of the stimulus. These commissural neurons, some of them propriospinal, transmit horizontal canal signals to the contralateral ventral horn, presumably to motoneurons, as well as to more caudal levels of the spinal cord.

    Anomalous nuclear spin-lattice relaxation in copper small particles (1989)
    Springer
    The European physical journal 12 (1989), S. 415-416

    Notes: Abstract Anomalously long nuclear spin-lattice relaxation time is expected in small metallic particles when the life time width of the conduction electron energy levels is smaller than their mean spacing. A new method for setting nuclear magnetization to zero is developed in order to measure the relaxation time in Cu small particles. The anomaly is observed in the relaxation of63Cu in the particles with the diameters smaller than 100 A at temperatures below 0.5 K.

    Pyrolysis-gas chromatography of carbonate apatites used for sintering (1995)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Gas chromatography was employed to quasi-continuously determine the amount of carbon dioxide that evolved from carbonate apatite specimens during sintering. Assuming that the carbonate in the specimens decomposed to carbon dioxide on a mole-for-mole basis, the determination of the carbon dioxide evolved allowed for the determination of the amount of carbonate that remained in the specimens during different stages of sintering. Previously, this measurement could be carried out only after sintering was completed. Comparison of data obtained from specimens compacted isostatically at 600 MPa for sintering with powder specimens indicated that the amount of carbonate remaining in the sintered apatite mass strongly depended on heating rates, heating temperatures, and holding-time intervals. © 1995 John Wiley & Sons, Inc.
