Scientific interests: Metacognition, introspection & self-monitoring; Pathophysiology of psychiatric disorders linked to basal ganglia dysfunctions, in particular compulsive behaviors (OCD); Therapeutical mechanisms in Cognitive-Behavioral Therapy (CBT) and Mindfulness-Based Therapy. Evolutionary cognitive neuroscience of social processes and emotions; Techniques used: Human behavioral experiments; Brain Imaging: Magnetic Resonance Imaging (MRI) & Functional MRI; Human electrophysiology: electroencephalography (EEG), magnetoencephalography (MEG), local field potentials (LFP). Keywords: metacognition, emotion, fMRI, deep brain stimulation, working memory, prefrontal cortex, basal ganglia Scientific agenda My research explores the neurocognitive processes involved in self-representation and self-evaluation through a wide range of techniques and approaches, focusing in particular on the neural bases of metacognition, i.e., the psychological processes that enable one to monitor and regulate one’s own cognitive activity, e.g. the confidence one has in a decision just-made and/or the action one may take to assuage one’s doubts. Despite a wealth of behavioral psychology and psychophysics research, the brain mechanisms participating to metacognition have only recently garnered interest (Fleming et al., 2012; Dehaene, 2011). Concurrently, metacognitive processes have also been implicated in psychopathological models of mental disorders (Wells, 1995) and in evolutionary theory of human cognition (Carruthers, 2008). I explore these issues through experimental studies combining behavioral and neurofunctional methodologies (fMRI, local field potentials, EEG/MEG) in healthy participants as well as neurological and psychiatric patients treated with deep-brain stimulation or other types of interventions (e.g. psychotherapy). In my scientific work, I primarily focus on the role of cortical regions (encompassing the anterior cingulate, orbitofrontal, ventro-medial and rostral prefrontal cortices) along with the basal ganglia for these structures pertain to functional cortico-subcortical loops that have been associated with performance-monitoring and behavioral control. One central issue pertains to the mechanisms through which metacognitive information might be derived from ongoing neural activity to allow flexible behavior and adaptive decision-making, in laboratory tasks – e.g. when deciding if enough sensory evidence has been collected to decide whether one is seeing leftward or rightward motion in a random dot displays – as well as in more ecological experimental settings, such as when confronting self-confidence with external sources of evidence (from feedback or from other individuals). With the BEBG team, I take benefit of clinical trials conducted around deep-brain stimulation to explore possible dysfunctions of metacognitive processes and their neuro-behavioral correlates in neuropsychiatric disorders but also to test the causal role of targeted structures, e.g. the subthalamic nucleus (STN). Obsessive-compulsive disorder which is characterized by “pathological doubt” thus represents a potent psychopathological model. For example, I developed a perceptual decision task which incorporates confidence-ratings that are used to derive quantitative measures of introspective monitoring in OCD patients over the course of a clinical-trial of STN-DBS. This allows assessing the possible role of dysfunctional metacognition in the etiology of the disease and its recovering through subthalamic stimulation. This line of research also participate in the identification of transnosographic behavioral phenotypes, such as compulsivity (seen in OCD but also in drug addiction) that appears associated with blunted introspective awareness of one’s motivational processes. I also participate to translational […]

Keywords Sociology of science, citizen science, patient association, mental disability compensation, clinical research, evaluation of psychotherapies, Obsessive Compulsive Disorder, neuroscience. Resume I conducted a project “Institution-Citizen Partnership for Research and Innovation” (PICRI) in collaboration between BEBG team and the french Association of people suffering from obsessive compulsive disorder (OCD) and their relatives (AFTOC). I have set up, coordinated and supervised a longitudinal research design to evaluate the effectiveness of an innovative treatment (using computerized tools) and cognitive behavioral therapy (CBT) for patients with OCD verification (which is the subject of a scientific article). I was the scientist in charge of this clinical trial on changes in brain activity in patients with OCD CBT. I also conducted an online survey to study the representations that have OCD patients, relatives, health professionals and the general public (the survey is the subject of a book chapter). I did a bi-disciplinary thesis of sociology of  science whose objective was to report the factory process of  scientific knowledge through an ethnographic approach and observation of a team of “big neuroscientists” which was also the subject of an article. I’m currently running a project in partnership with the research center of medicine, science, health, mental health, society (Cermes3-CNRS) and the Brain and Spine Institute (ICM). Our project is anchored in a process that has been developed in recent years, due to sociological, legislative and technological developments, and that is seeking solutions to improve the lives of people with OCD not only by medical means referred to therapeutic, but by all means to compensate disability and quality of life impairments generated by the disorder. The aim is to exploit the potential of the major innovations in the field of localized connected mobile computing, that is to say, the “smartphones”, the “Smarthomes” and connected objects. Our project is registered in a broader movement to engage users or future users of technology solutions in the design of these solutions, right from the earliest stages of design. This movement is generally designated by the terms of participatory design, participatory innovation, open innovation, crowdsourcing … To support this process participatory innovation we have chosen to implement this platform available on the Web to collect, organize, synthesize, present, monitor and develop the ideas proposed by all persons affected by OCD problem (people with first OCD but also their relatives, carers -psychiatres, psychologists, neurologists, occupational therapists …, researchers, social workers …). At the same time, we are conducting ethnographic and anthropological monographs at the home of people with OCD and their families. Finally, we develop smartphone apps of Ecological Momentary Assesment (EMA) to allow people with OCD self-assessment in a perspective of empowerment, and improvement of reflective understanding of their problems, and practitioners to access to contextualized information and so far to adapt their therapeutic strategies.

Philippe Domenech

I am assistant professor in psychiatry in the department of functional neurosurgery of Henri Mondor teaching hospital in Paris. I specialize in severe and treatment refractory obsessive compulsive disorder, Parkinson disease and deep brain stimulation. I study decision-making processes and their contextual regulation. I’m applying model-based and model-free analytic methods to fMRI, EEG and S-EEG data to establish an algorithmic mapping of the Human brain engaged in simple decisions. I’m also using pharmacological manipulations and deep brain stimulation to investigate the neural circuitry underpinning the decision-making process. More recently, I have been trying to extend this approch to executive functions such as exploration/exploitation tradeoff. Previously, I did a PhD in Cognitive Neurosciences under Jean-Claude Dreher at the Centre de Neuroscience Cognitive (CNRS) in Lyon and obtained a MD in psychiatry from Lyon Est University. Then, I have worked for three years as a post-doc researcher in Etienne Koechlin’s Lab (ENS/INSERM) which is based at the “Ecole Normale Superieure“.

Eric Burguière

Eric Burguière is working with mouse models of repetitive behaviors in the BEBG team. During his PhD thesis (obtained from Collège de France / Sorbonne University in December 2006), he first learned to study and analyze mutant mice behavior by designing paradigms to study motor adaptation. Then, during his post-doctoral period in the Graybiel laboratory at the Massachusetts Institute of Technology (2007-2012), he studied mouse models of disorders affecting motor execution as Parkinson disease and OCD-spectrum disorder. He use and develops different methodology such as  multi-unit electrophysiological recordings and optogenetics technology to better probe and understand the pathophysiology of these disorders (Burguiere et al., Science, 2013). He is currently a principal investigator at the Brain and Spine Institute (ICM) in Paris and supervise several project which aim at understanding the neurophysiological basis of repetitive behaviors.   5 Main recent publications E.
