- Dopamine, paranormal belief, and the detection of meaningful stimuliPeter Krummenacher
University Hospital Zurich, Switzerland
J Cogn Neurosci 22:1670-81. 2010..These results stand at odd to the common view that DA generally improves signal-to-noise ratios. Paranormal ideation seems an important personality dimension and should be assessed in investigations on the detection of signals in noise...
- [Prefrontal cortex mediated control of expectations in placebo analgesia]P Krummenacher
Collegium Helveticum, ETH Zürich and Universität Zürich
Schmerz 25:440-3. 2011..These findings suggest that expectation-induced placebo analgesia is mediated by symmetric prefrontal cortex function. Possible implications for medical practice and clinical trial research will be discussed in the article...
- Placebo-mediated, Naloxone-sensitive suggestibility of short-term memory performanceJair Stern
Collegium Helveticum, ETH and University of Zurich, Schmelzbergstr 25, 8092 CH Zurich, Switzerland
Neurobiol Learn Mem 95:326-34. 2011..These results indicate an opioid-mediated placebo effect within a circumscribed cognitive domain in healthy volunteers...
- Implicit learning of sequential bias in a guessing task: failure to demonstrate effects of dopamine administration and paranormal beliefJohn Palmer
Department of Neurology, University Hospital Zurich, Zurich, Switzerland
Conscious Cogn 16:498-506. 2007..None of the hypotheses were supported by the data. It is suggested that a simple binary guessing task with a focus on prediction accuracy during early trials should be considered for future explorations...
- Prefrontal cortex modulates placebo analgesiaPeter Krummenacher
Collegium Helveticum, Schmelzbergstrasse 25, CH 8092 Zurich, Switzerland
Pain 148:368-74. 2010..While rTMS did not affect pain experience, it completely blocked placebo analgesia. These findings suggest that expectation-induced placebo analgesia is mediated by symmetric prefrontal cortex function...
- Naloxone modulates visual judgments of similarity but not dissimilarityPeter Krummenacher
Department of Neurology, Neuropsychology Unit, University Hospital Zurich, 8091, Zurich, Switzerland
Cogn Affect Behav Neurosci 13:567-74. 2013..The task introduced here could be used for the implicit study and quantification of subtle affective-cognitive processes beyond the level of mere questionnaire data...
