    DEBT AND TAXES: EMPIRICAL EVIDENCE (1985)

    Notes: The literature currently proposes several capital structure theories whose predictions are generally mutually exclusive. Empirical testing to date has been subject to serious conceptual and econometric problems. The present study, which is carried out on a cross-section of industrial firms, attempts to overcome several deficiencies in earlier studies. Although the results are more consistent with Miller's 1977 hypothesis that the value of the firm is independent of leverage in the absence of leverage-related costs than they are with those theories which predict a value-maximizing optimum debt level, there is significant evidence that the value of the firm may be negatively related to leverage over a broad range of debt usage.

    Dynamic properties of renshaw cells: Equivalence of responses to step changes in recruitment and discharge frequency of motor axons (1982)
    Springer

    Notes: Abstract In decerebrate cats, the dynamic responses of Renshaw cells to step changes in input were determined seperately both for changes in the number of α-axons excited and for changes in the frequency at which they were stimulated. Together, these two input variables to the Renshaw cells describe the level of activity in the motor output from the spinal cord. In either case, the dynamic responses of the interneurons depend only on their static activity before and after an input step occurs, but are otherwise indistinguishable. This favors the interpretation that the two input variables are equivalent under dynamic conditions, i.e., Renshaw cells respond to total motor output.

    The influence of bacterial collagenase on regeneration of severed rat sciatic nerves (1992)
    Springer
    Acta neurochirurgica 119 (1992), S. 121-127 
    Details
    ISSN: 0942-0940
    Keywords: Collagenase ; nerve regeneration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Regeneration of peripheral nerve fibers is impeded by the formation of scar tissue at the site of injury. The possible beneficial effect of collagenase on nerve regeneration was studied using clinical, neurophysiological (evoked potentials) and histological (nerve fiber counts) methods. The sciatic nerves of rats were transected and the severed ends abutted and sewn together. In one series, the area about the lesion was covered with fibrin adhesive and infused with either isotonic saline (controls) or collagenase (treatment group). In the other series, the severed ends of the nerve were inserted into a silicone tube and separated by a collagen plug, which was infused with either saline or collagenase. Compared to the controls, the treated animals showed a significant improvement of clinical and neurophysiological parameters. After 3 months of observation, the collagen content of the transection site was reduced, and in the silicone series, the total number of myelinated axons 5mm distal to the site of transection was increased, while the fiber diameter distribution was unchanged.

    Static input-output relations in the spinal recurrent inhibitory pathway (1981)
    Springer
    Biological cybernetics 40 (1981), S. 223-231 
    Details
    ISSN: 1432-0770
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Computer Science , Physics
    Notes: Abstract The static discharge rate of Renshaw cells (studied in deafferented, intercollicularly decerebrate cats) has a nonlinear dependence on the frequency of trains of stimulus impulses to α-motor axons in the ventral root. This dependence is well described by a rectangular hyperbola that approaches saturation with increasing stimulus frequency. The tendency to saturate is independent of the number of motor axons exciting a Renshaw cell. On average, the stimulus frequency at which the discharge rate reaches half its saturation value lies between 10 and 15 Hz. The effect of Renshaw cell activity — measured as the antidromic inhibition of individual α-motoneurons — reflects the form of the static frequency characteristics. An electric circuit analog of the Renshaw cell membrane is presented which serves to explain the qualitative features of the static input-output relations; the nonlinearity is the result of synapses with linear properties acting together at the cell membrane.

    Dynamic properties of Renshaw cells: Frequency response characteristics (1977)
    Springer
    Biological cybernetics 27 (1977), S. 175-184 
    Details
    ISSN: 1432-0770
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Computer Science , Physics
    Notes: Abstract The dynamic properties of Renshaw cells located in the lumbar spinal cord of intercollicular decerebrate cats were measured. The responses of these interneurones were recorded extracellularly, while the ventral root was stimulated with sinusoidally frequency-modulated trains of electrical pulses. The frequency of the Renshaw cell discharges resulting from such stimulation varied sinusoidally. The amplitude of modulation about the average (or “carrier”) rate of discharge exhibited a linear dependence on the modulation amplitude of the stimulus pulse train. Renshaw cells were able to follow modulated stimulus trains in the entire range of modulation frequencies (0.2 to 80 Hz) encompassed by the present study. Above modulation frequencies between 20 and 50 Hz, the amplitude of modulation of the responses declined. Frequency responses measured at low average frequencies of the stimulus pulse train (centre frequencies 30 and 40 Hz) showed comparatively little dependence on modulation frequency. The higher the centre frequency, however, the greater was the enhancement of the modulation amplitudes at high modulation frequencies compared with those observed at low modulation frequencies. Some aspects of the functional implications of these results are considered and an approximate formula for the transfer function of Renshaw cells is presented.

    Decrease of antidromic inhibition due to orthodromic tetanic stimuli (1974)
    Springer

    Notes: Summary Antidromically tested Renshaw cells and the antidromic inhibition of monosynaptic extensor reflexes were recorded in decerebrate cats before, during, and after intermittent tetanic stimulation of afferents. During tetanization, the amount of inhibition decreased markedly, as did the excitability of Renshaw cells. We suggest that the diminished antidromic inhibition during PTP reflects an inhibition of Renshaw cells.
