“…All seven of the schizophrenics with predominantly negative symptoms had suffered severe delivery complications and were ANS nonresponders. This supports the hypothesis that perinatal complications could be a causative factor in third ventricle enlargement, which may contribute to electrodermal hyporesponsiveness (Cannon et al, 1988), 241 and is also a typical computer tomographic abnormality in schizophrenics (Cannon, Mednick, & Parnas, 1989). Contrarily, in another subsample of 160 schizophrenics from the Copenhagen study, 6 of the 8 patients with predominantly positive symptoms had suffered severely instable environments for growing up and evidenced high levels of ANS responsiveness.…”

A quartercentury later the scientific study of psychology also originated in Germany. Over time, however, the focus of psychological research, including the then new field of psychophysiology, shifted to the United States and Great Britain. This trend to the dominance of the United States and Great Britain was prolonged by the devastation of World War II and its aftermath in Germany (and elsewhere in continental Europe). Slowly at first and then more rapidly, German psychological science, including psychophysiology, recovered. For several decades German psychophysiologists have been a major force in psychophysiology. With the publication of the first English edition of this book in 1992, it became essential for electrodermal researchers worldwide again to learn from our German colleagues.When I came into psychophysiology in the mid-1960s, electrodermal activity was the most common system studied. Because of its popularity, a large literature had emerged on the physiological mechanisms producing these changes in the electrical properties of the skin and on the best methodology for recording them. Major reviews and/or chapters had been published or soon were to be published by Peter Venables and Irene Martin, Robert Edelberg, and David Lykken. Later reviews and articles were published by Venables and Margaret Christie, and by me. A chapter in 1990 by Michael Dawson, Anne Schell, and Diane Filion was especially noteworthy for its coverage of the psychological applications of electrodermal measures.Note that all these publications were journal articles and chapters and that most of them focused almost entirely on mechanisms and methodology. The publication of this book, first in German and then in English, provided the first book on electrodermal activity, and one that extensively covers psychological applications as well as mechanisms and methodology. Again to quote David Lykken back in 1992, "The return of German scholarship to what I shall loftily call the high table of psychophysiology is exemplified by this fine book, the most comprehensive treatise on the electrodermal system to appear in any language . . ." I completely agree with v that evaluation. Professor Boucsein's outstanding scholarship has produced a book of such breadth of coverage ...

“…236 It could be further speculated that different EDA parameters are related to different pathogenetic factors Cannon et al (1988),. using a subsample from the Copenhagen study, found that individuals with enlarged third ventricles (which may point to hypothalamic and/or amygdalar deficits) showed significant overall reductions in EDR amp.…”

“…It may also be due to disproportionate volume loss in localised, periventricular structures (Harrison, 1999). Disturbance of the autonomic nervous system (ANS) has been shown to be associated with negative symptom schizophrenia (Frith et al , 1979) and with widening of the third ventricle (Cannon et al , 1988). Widening of the third ventricle has been shown to be associated with negative symptoms (Andreasen et al , 1982).…”

“…Cannon e.a. 32 vonden in een gemcngde groep van schizofrene patienten en 'high-risk'-proefpersonen (personen met een schizofrene mocder) dat 'non-responding* gepaard gaat met een vergrote derde ventrikel. De auteurs suggeren dat vergroting van het derde ventrikel een beschadiging van de anterieure hypothalamus impliceert aangezien de basis van deze vertrikel vvordt omringd door de anterieure hypothalamus.…”

Skin conductance is a psychophysiological parameter that reflects fundamental processes such as attention and arousal. The present study explored whether deviations in skin conductance activity are associated with severity of schizophrenic symptoms. For this purpose, Skin Conductance Responses (SCRs) to discrete stimuli (80 dB noises) and Skin Conductance Levels (SCLs) of 37 schizophrenic patients and 31 healthy volunteers were recorded. In accordance with previous studies, schizophrenic patients were found to be hyporesponsive compared to healthy controls. More specifically, almost half of the patients (46%) did not react with any SCR to the first 3 stimuli, whereas only 10% of the control group exhibited such a non-responding. Accordingly, the mean amplitude of the first 3 SCRs - as measured in u Siemens - was found to be significantly lower in patients compared to controls. As well, mean SCL was found to be (marginally) elevated in the patient group. This was especially the case for patients who did exhibit SCRs. In the patient group, a negative correlation was found between amplitude of SCRs and symptom severity. This association was mainly carried by a significant correlation between positive symptoms and reduced SCRs. The clinical relevance of these findings is discussed in detail.
