    Notes: Abstract The plasma decomposition of NH3 has been studied as a function of the residence time, power input, and pressure. The process follows apparently zero-order kinetics, which can be interpreted on the basis of a kinetic mechanism involving as initial step the rupture of an N-H bond from vibro-rotationally excited modecules. Simultaneous spectroscopic observations of the emission light due to electronically excited NH2, NH, H, and N2 have been used to confirm the suggested mechanism and to show that NH2 and NH are successive intermediate species and that the final step of the decomposition process is the bimolecular recombination NH+NH→N2+H2.

    Evidence of a contralateral motor influence on reciprocal inhibition in man (1992)
    Springer
    Journal of neural transmission 4 (1992), S. 257-266 
    Details
    ISSN: 1435-1463
    Keywords: H reflex ; reciprocal inhibition ; contralateral movement ; cutaneous stimulation ; IA interneurone

    Notes: Summary The role of contralateral movement on both H reflex and reciprocal inhibition was studied. In normal men H reflex was induced by median nerve stimulation. Reciprocal inhibition was achieved through stimulation of the antagonist radial nerve. On this basis the effects of contralateral arm movement were analized. Furthermore the putative influence of exteroceptive origin was also verified by means of digit stimulation. Results showed that contralateral arm movement did not affect H reflex amplitude; on the contrary, it was able to enhance reciprocal inhibition induced by extensors on flexors. Study of cutaneous afferents demonstrated that contralateral digit stimulation failed to elicit modifications on both H reflex and reciprocal inhibition. On the other hand, ipsilateral digit stimulation lowered H reflex amplitude and increased the degree of reciprocal inhibition. Experimental findings underline the possibility that an informational array reaches the contralateral IA interneurone: therefore a mutual (bilateral) interaction among IA interneurones may accordingly be hypothesised.

    Bilateral reciprocal organisation in man: focus on IA interneurone (1994)
    Springer
    Journal of neural transmission 96 (1994), S. 31-39 
    Details
    ISSN: 1435-1463
    Keywords: H reflex ; reciprocal inhibition ; IA interneurone ; upper limb

    Topics: Medicine
    Notes: Summary The H reflex of flexor carpi radialis and radial-induced reciprocal inhibition were recorded in normal subjects during conditioning stimulation of the contralateral median or radial nerves. It was found that stimulation of the contralateral median nerve enhanced the degree of reciprocal inhibition exerted by the radial nerve on the median nerve, while contralateral radial nerve stimulation reduced the reciprocal inhibition exerted by the extensor on the flexor. In two subjects in which a pure extensor H reflex was recorded specular features were observed following contralateral median and radial stimulation. These findings are considered to be the electrophysiological manifestation of contralateral modulation of reciprocal inhibition, which is likely to act at the level of the IA interneurone.
