Session:
Computational and Psychological mechanisms underlying Placebo Effects

Christian Büchel,
Prof.

University Medical Center Hamburg-Eppendorf Germany

Christian Büchel, Prof.

Chair and introduction

Christian Büchel is a Professor for Cognitive Neuroscience and the Director of the Department for Systems Neuroscience at the University Medical Center Hamburg-Eppendorf in Germany.
He investigates how higher cognitive processes such as learning are anchored in functional connections of the brain. His lab is mainly interested in pain, fear and decision making. Christian aims to identify mechanisms behind these phenomena using a multi-level approach: analysis of behavior and autonomic responses, computational modeling of the underlying algorithmic and neural processes, multimodal neuroimaging (fMRI and EEG) of these processes, and pharmacological challenges to investigate the causal role of specific neurotransmitter systems. His work not only contributes to our understanding of basic neuroscience mechanisms, but also provides novel ideas and approaches in clinical neuroscience, which could eventually improve prevention, diagnosis, prognosis and disease progression assessment in neuropsychiatric disorders including chronic pain.

Klaas Enno Stephan,
Prof.

University of Zurich and ETH Zurich, Switzerland

Klaas Enno Stephan, Prof.

Klaas Enno Stephan is a Professor for Translational Neuromodeling & Computational Psychiatry at the University of Zurich and ETH Zurich in Switzerland.
His scientific work covers the entire translational pipeline, from the development of disease theories via the creation of computational methods to their application in clinical studies. One of his central goals is the development of clinically useful “computational assays” for psychiatry and psychosomatics. Based on generative models of brain activity and behavior, his hope is that such assays will support more precise diagnostics and individualized treatment recommendations, leading to a transformation of clinical practice and redefinition of mental diseases. His track record includes pathophysiological theories of schizophrenia, fatigue and depression, the development of open source and widely used computational tools (e.g., for investigating brain connectivity and Bayesian model selection) as well as numerous studies on psychiatric and psychosomatic disease mechanisms.

Sydney Trask,
PhD

Department of Psychological Sciences, Purdue University, USA

Sydney Trask, PhD

Sydney Trask is an Assistant Professor for Neuroscience and Behavior at the Department of Psychological Sciences at Purdue University in the US.
She is interested in the ways the brain encodes, stores, retrieves, and updates memory, particularly in understanding memory for context, or the environment in which events take place. „Successful encoding and retrieval of context allows us to select and guide our behavior in a way that encourages situationally appropriate responding. However, alterations in this type of learning and memory are common in symptomology that underlies several neuropsychiatric disorders, ranging from PTSD to age-related dementia. Understanding how memory for context is formed, retrieved, and altered at both the circuit and molecular level, will provide one crucial step forward to treatments aimed at reducing maladaptive behaviors stemming from contextually inappropriate behaviors.

Luana Colloca, PhD

Luana Colloca is an MPower Distinguished Professor at the University of Maryland in the School of Nursing in the US. 
Luana leads a research portfolio exploring endogenous pain perception, processing, and modulation in which the expectancy of analgesic relief, which can actually activate endogenous systems, is explored from a psychoneurobiological perspective from genetics to brain imaging. This also includes placebo/nocebo effects and other nonpharmacological interventions such as virtual reality. Her work on the neurobiological mechanisms of placebo and nocebo effects with an multifaced approach, including psychopharmacological, neurobiological and behavioral approaches, raises the possibility of unfolding the mechanisms of expectancy-induced analgesia with potential implications for pain management.

Karin Jensen,
Prof.

Department of Clinical Neuroscience, Karolinska Institute, Sweden

Karin Jensen, Prof.

Karin Jensen is an Associate Professor for Clinical Neuroscience at the Department of Clinical Neuroscience at the Karolinska Institute in Sweden. 
Her research group focuses on brain mechanisms involved in the experience of pain and placebo effects. Karin‘s work has challenged existing models of the placebo effect and contributed novel scientific data demonstrating that (a) placebos work outside of conscious awareness, (b) placebos work among patients with severe intellectual disabilities, and (c) placebo effects are shaped by subtle social cues between a patient and health-care provider. Karin adopts an evolutionary perspective of the placebo effect and studies placebos in previously understudied contexts such as psychotherapy, surgery and intellectual disability.

Alia Crum,
PhD

Stanford School of Humanities and Sciences, USA

Alia Crum, PhD

Alia Crum is an Associate Professor for Psychology and Medicine at Stanford School of Humanities and Sciences in the US.
Her research focuses on how changes in subjective mindsets - the lenses through which information is perceived, organized, and interpreted - can alter objective reality through behavioral, psychological, and physiological mechanisms. Her work is also inspired by research on the placebo effect, a remarkable and consistent demonstration of the ability of the mindset to elicit healing properties in the body. She is interested in understanding how such mindsets affect important outcomes outside the realm of medicine, in the domains of behavioral health and organizational behavior. More specifically, she aims to understand how mindsets can be consciously and deliberately changed through intervention to affect organizational and individual performance, physiological and psychological well-being, and interpersonal effectiveness.
