    Description / Table of Contents: Summary Using special electronic averaging machines it is possible to measure with extracranial electrodes stimulus-locked cortical potentials following pain stimulation in human subjects. In this manner objective electrophysiological measurements may be correlated with psychophysic results. 1. Above individual threshold the cortical response following pain stimulation is represented by nearly one surface-positive deflection with a duration of 50–200 msec (amplitude 4–20 μV) and a latency of 75–120 msec, both increasing with the increase of stimulus strength. 2. Stimulus-locked responses below individual threshold with a duration of about 60 msec and a latency of 50 msec prove the existance of the so called “prepain sensation area”. 3. Simultaneous tone and pain stimulation results a response which shows the form of that following pure tone stimulation. 4. Comparing the intensity course of equivalent psychophysic results with the dependance on stimulus strength of the amplitude of the measured slow evoked components in man there is a remarkable identity of the steepness (exponent of power function: 3,12±0,4).
    Notes: Zusammenfassung Mit Hilfe elektronischer Auswerteanlagen werden reizsynchrone corticale Antworten am wachen Menschen bei Schmerzreizung extracranial abgeleitet und damit objektive elektrophysiologische Korrelate psychophysischen Untersuchungen gegenübergestellt. 1. Die corticale Reizantwort bei Schmerzreizung besteht im subjektiv überschwelligen Bereich grob aus einer oberflächenpositiven Potentialschwankung mit einer reizstärkeabhängigen Dauer von 50 bis 200 msec (Amplitude 4–20 μV) und einer Spitzenlatenz von 75–120 msec. 2. Reizsynchrone Potentialschwankungen einer Dauer von 60 msec und einer Spitzenlatenz von 50 msec im subjektiv unterschwelligen Bereich deuten auf das Vorhandensein einer sogenannten Vorschmerzgefühlszone hin. 3. Bei gleichzeitiger akustischer Reizung und Schmerzreizung dominiert, mit subjektiven Empfindungen übereinstimmend, signifikant der akustische Charakter der Komponenten des langsamen Rindenpotentials. 4. Ein Vergleich psychophysisch gewonnener Intensitätsgänge bei elektrischer Schmerzreizung mit der Abhängigkeit der Amplitude der corticalen Antwortpotentiale von der Reizstärke zeigt nahezu identische Steilheit (Exponent der „power function“: 3,12±0,4).

    Notes: Abstract: Thermal conductivity κ xx(T) under a field is investigated in d x2 - y2-wave superconductors and isotropic s-wave superconductors by the linear response theory, using a microscopic wave function of the vortex lattice states. To study the origin of the different field dependence of κxx(T) between higher and lower temperature regions, we analyze the spatially-resolved thermal conductivity around a vortex at each temperature, which is related to the spectrum of the local density of states. We also discuss the electric conductivity in the same formulation for a comparison.
