“…Thus, the lower SCL, OR and SCOR conductance amplitudes are, the larger the scores in BDI, STAI-E and STAI-R. Some authors have observed similar results [34,42], but other studies have not detected any correlation [26,38,43,44]. In the present research, the depressive sample displayed high scores in STAI which would be able to reflect elevated anxiety.…”

“…Some researchers have shown faster habituation of electrodermal orientation responses in depressive patients [18][19][20][21][22][23][24][25]. Other studies have shown no or slower habituation in depressive patients 26,27]. It is possible that in our investigation no differences were observed because we used nonsignificant stimuli (tones) and carried out electrodermal registers during rest.…”

“…Faster habituation of electrodermal orientation responses has been demonstrated in depressive patients [18][19][20][21][22][23], even when the stimulus was a strong tone near the aversive threshold [24,25]. Nevertheless, in some studies depressive patients have shown no or slower habituation than normal [26,27].…”

The aim of the present study was to investigate further into habituation and sensitization processes in depressive disorders. The depressive subjects were 27 outpatients. All of them were diagnosed according to DSM-III-R criteria. Controls were 27 normal subjects. The amplitudes of electrodermal responses and the basal levels were recorded during a stimuli series of 15 80-dB tones and of 1 100-dB tone in the 11th trial. The depressive patients displayed lower basal conductance levels and lower conductance amplitudes in orienting responses to the first stimulus and to stimulus change. No differences were found in conductance response amplitudes of stimuli series, although a tendency towards smaller conductance amplitudes in depressive patients was observed before stimulus change. A trend towards habituation was detected in both groups, but no differences between them were present, neither the habituation velocity of depressives was found to be unlike normals. Our results display lower responsivity in depressive patients, which reflects alterations in the sensitization process.

“…Unexpectedly, electroconvulsive treatment significantly lowered the SCL in depressives, but neither changes in EDA nor changes in HR were related to differences in subsequent clinical improvement. Storrie, Doerr, and Johnson (1981) could not demonstrate an influence of psychopharmacological treatment with antidepressants or antipsychotic medication on EDA in depressives. During resting and during performance of three valsalva maneuvers, both SCL and SCR amp.…”

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 ...

“…48 Electrodermal reactivity is under genetic influence, with a heritability of ∼50% in healthy twins, 49 and is state independent. 50 In addition, an electrodermal response has been correlated with decision making in the Iowa gambling task in healthy subjects. 51 Therefore, electrophysiological hyporesponsivity may be an endophenotype partially linked with poor decision-making abilities.…”

The neuroscience of suicidal behaviors: what can we expect from endophenotype strategies?

et al. 2011

Vulnerability to suicidal behavior (SB) is likely mediated by an underlying genetic predisposition interacting with environmental and probable epigenetic factors throughout the lifespan to modify the function of neuronal circuits, thus rendering an individual more likely to engage in a suicidal act. Improving our understanding of the neuroscience underlying SBs, both attempts and completions, at all developmental stages is crucial for more effective preventive treatments and for better identification of vulnerable individuals. Recent studies have characterized SB using an endophenotype strategy, which aims to identify quantitative measures that reflect genetically influenced stable changes in brain function. In addition to aiding in the functional characterization of susceptibility genes, endophenotypic research strategies may have a wider impact in determining vulnerability to SB, as well as the translation of human findings to animal models, and vice versa. Endophenotypes associated with vulnerability to SB include impulsive/aggressive personality traits and disadvantageous decision making. Deficits in realistic risk evaluation represent key processes in vulnerability to SB. Serotonin dysfunction, indicated by neuroendocrine responses and neuroimaging, is also strongly implicated as a potential endophenotype and is linked with impulsive aggression and disadvantageous decision making. Specific endophenotypes may represent heritable markers for the identification of vulnerable patients and may be relevant targets for successful suicide prevention and treatments.
