The plasticity of a synapse in the molluscan peripheral nervous system was examined under a variety of experimental, physiological, and pharmacological conditions. These studies employed the isolated salivary glands and attached buccal ganglia of the freshwater snail Helisoma. Action potentials evoked in buccal neuron 4 normally evoke a large excitatory postsynaptic potential (EPSP) which drive...

The purpose of this study was to investigate the relationship between quantitative electroencephalograph relative amplitude, relative power and hypnotic susceptibility. Hypnotic susceptibility, measured by the Wickramasekera Experience Inventory, was found to be positively correlated with QEEG theta relative amplitude (r = 0.260, p < .10). In addition, hypnotic susceptibility was found to be ne...

Tremor rating scales (TRSs) are used commonly in the clinical assessment of tremor, but the relationship of a TRS to actual tremor amplitude has never been quantified. Consequently, the resolution of these scales is unknown, and the clinical significance of a 1-point change in TRS is uncertain. We therefore sought to determine the change in tremor amplitude that corresponds to a 1-point change ...

Regularized adelic formulas for gamma and beta functions for arbitrary quasicharacters (either ramified or not) and in an arbitrary field of algebraic numbers are concretized as applied to one-class quadratic fields (and to the field of rational numbers). Applications to 4-tachyon tree string amplitudes, to the Veneziano (open strings) and Virasoro (closed strings) amplitudes as well as to mass...

We present results for the photoproduction helicity amplitudes of excited baryons obtained in the context of the 1/Nc expansion of QCD. The results show that, in order to get a satisfactory description of the observed photoproduction amplitudes, the sub-leading corrections in 1/Nc are important. We also find that, while onebody effective operators are dominant, there is some evidence for the ne...

New results from inelastic two-body scattering reactions are reviewed. Although predictions of SU(3), factorization and simple Regge theory are found to be qualitatively in agreement with the data, direct channel or absorption effects afford the simplest interpretation of the detailed features of the scattering amplitudes.

A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave Kπ amplitude as a function of Kπ invariant mass. These are compared with results from K − π + elastic scattering, and the prediction of the Watson theorem , that the phase behavour be the same below Kη ′ threshold, is tested. Contributions from I = 1 2 and I = 3 2 are not reso...

In this letter we propose exact three-point correlation functions for N = 1 super-symmetric Liouville theory. Along the lines of [12] we propose a generalized special function which describe the three-point amplitudes. We consider briefly the so called reflection amplitudes in the supersymmetric case.

1. The aim of the study was to examine the effects of single doses of two antidepressants (desipramine and reboxetine) on three kinetic parameters (latency, amplitude, 75% recovery time) of the pupillary light reflex response. 2. Six healthy male volunteers participated in three experimental sessions at biweekly intervals. Each session was associated with one of three treatment conditions (plac...
