    Notes: Summary In anaesthetized rabbits, the medulla was surveyed with recording microelectrodes to identify different types of vestibulospinal tract neurones. Field potentials, unitary extracellular spikes and intracellular potentials were recorded during antidromic stimulation at C1 and C6 segments and during orthodromic stimulation through VIIIth nerve. The lateral and medial vestibulospinal tracts (LVST and MVST) were stimulated discriminately with the method developed in Appendix. On the basis of different axonal courses and conduction velocities, three major groups were distinguished for those cells which were activated monosynaptically by the primary vestibular afferents; 1. fast conducting LVST; 2. fast conducting MVST; and 3. slowly conducting MVST. Three other groups were discriminated for those cells which received only a polysynaptic or no action from primary vestibular afferents. These were; 4. fast conducting LVST; 5. slowly conducting LVST and 6. slowly conducting MVST. All of these six types of VST cells were represented within Deiters' nucleus. Only a relatively small number of MVST cells were found in the medial vestibular nucleus.

    Synaptic linkage in the vestibulo-ocular reflex pathway of rabbit (1971)

    Notes: Summary Microelectrodes were inserted into IIIrd cranial nucleus of anaesthetized rabbit. IIIrd nucleus was identified by observing the field potentials evoked antidromically by stimulation of IIIrd cranial nerve. After stimulation of VIIIth nerve extracellular field potentials, spike potentials in secondary vestibular fibers, and postsynaptic potentials in IIIrd nucleus neurones were recorded. VIIIth nerve impulses either excite or inhibit IIIrd nucleus neurones postsynaptically with disynaptic latencies around 1.7 msec. By local stimulation of the medulla, it was found that the secondary vestibular impulses inhibiting IIIrd nucleus neurones are mediated by the superior nucleus. The excitatory impulses are relayed by the rostral half of the medial nucleus as well as a certain structure(s) relevant to the brachium conjunctivum. Preliminary pharmacological investigations on the inhibition of IIIrd nucleus neurones are reported.

    Absolute intensity ratios of Raman lines of benzene and ethylene derivatives with 5145 Å and 3371 Å excitation (1973)

    Notes: Absolute Raman intensities of benzene and ethylene derivatives were measured in the vapour phase with 5145 Å and 3371 Å excitation. Intensity increase of benzene 992 cm-1 band, which has been frequently used as an intensity standard, was found to be much smaller than expected. The observed intensity increases of ethylene derivatives nicely agree with the theory by assuming the contributing virtual states are the lowest allowed 1π, π* state.

    Notes: The depolarization ratios of the C=C stretching vibrational Raman lines of C2Cl4, C2HCl3, trans-C2H2Cl2 were measured using visible and UV lasers. The depolarization ratios increased evidently from visible to UV excitation, and were discussed in relation to the ratio of the scattering tensor components.
