Palmar skin sweating vs. palmar skin resistance and skin potential.

Overt palmar surface sweating produces positive component of palmar skin potential responses

“…Sweating responses were not observed at all in the presence of SPR negative waves in our study, which contradicts the findings of Wilcott (1962). This contradiction may be attributable to the abovementioned differences in the sensitivity and reliability of the methods employed for measuring sweating.…”

“…Several studies have attempted the simultaneous recording of sweating and skin resistance responses (SRRs) which exhibit only monophasic simple variations, and reported correlations of 0.8 to 0.9 between these factors (Adams & Vaughan, 1965;Wilcott, 1962). These studies suggest a 1:1 correlation between the sweating volume and the SRR amplitude.…”

“…According to a study on latency in EDRs and latency in surface sweating (Wilcott, 1962) •\ correlations of 0.62 to 0.80 between sweating responses and negative SPR waves, and close correlations of 0.81 to 0.95 between sweating responses and positive SPR waves. It is true that the correlation between sweating and positive SPR waves was strong, but some correlations were also noted between sweating and negative SPR waves , and therefore, it is difficult to speculate on the association between sweating and negative or positive components of SPRs from these correlation coefficients.…”

The effect of perspiration on the sEMG amplitude and power spectrum

“…However, it is unknown if signal deterioration occurs sooner as a result of the signal being altered through a sweat pool located between the snaps of electrodes. Skin conductivity should be a reliable indicator of signal dampening since it has been shown to be highly correlated with sweat rate (Wilcott, 1962), but there are no studies that have looked at this relationship since this early study.…”

Die Objektivierbarkeit psychopharmakologischer Drogen am Beispiel von Metylperon

“…Die Ordinate gibt die Beschleunigungsfähig keit in G wieder (G = die einfache Erdbeschleunigung 9,81). In die sem Fall beträgt die Freisetzung der motorischen Kraft 7,8 G. Der Stoss eignet sich am besten zur Demonstration der maximalen Be schleunigungsfähigkeit, da wir in früheren Untersuchungen gesehen haben, dass beim Stoss in kürzester Zeit die meisten motorischen Einheiten zu einer integralen Entladung kommen (Birkmayer, 1943 man zur Ansicht, dass durch eine Permeabilitätsveränderung der Zell membran der Hautwiderstand absinkt (Wilcott, 1962). Unabhängig von der tatsächlichen physikalischen Veränderung besteht die Empi rie, dass verschiedene Reize (Pistolenschuss, Schmerzreize, Reiz worte) nach kurzer Latenzzeit zu einem Absinken des Hautwider standes führen, das von einem Wiederanstieg gefolgt ist (Fahrenberg, 1964 (Kugler, 1963).…”
