Plasticity and SubjectivitY "PSY"
The aim of our research is to determine the impaired mechanisms involved in subjective and intersubjective experiences as those observed in psychiatric conditions addictions, and more generally along a continuum ranging from normal to pathology. More specifically, we are interested in the pathophysiology of hallucinations, familiarity disorders, post-traumatic flashbacks, affective and cognitive biases, craving, suicidal ideas or body-schema illusions. This goal is notably achieved through the development of diagnosis tools that may help medical decision (e.g. for first-episode psychosis or after a suicide attempt), and the validation of non-pharmacological therapies for drug-resistant symptoms (e.g. neuroguided rTMS or fMRI-based neurofeedback for hallucinations, trauma-focused therapy). Finally, we are interested in how these subjective experiences can be affected by a stressful or protective environment, a dedicated treatment, etc. Such adaptations refer to what we call plasticity. To answer these different questions, we refer to experimental methods coming from the cognitive sciences, combined with advanced analyses of EEG/MRI signals and computational modeling. Our scientific projects are divided in four axes.

I am particularly interested in exploring the neural mechanisms involved from visual sensation to visual awareness. My research focuses on normal and impaired access to consciousness of visual information, using behavioral and functional brain imaging approaches. I am particularly interested in hallucinations and familiarity disorders in schizophrenia.

Project: Visuo-perceptual deficits in Severe Alcohol Use Disorder: Behavioral characterization and implications for the decoding of emotions.
This project studies the interactions between vision and emotions in people with severe alcohol use disorder (ASD), with a dual objective: (i) to determine whether the affective deficits observed in this population can be due, at least in part, to low level visual deficits; (ii) test, in a clinical population, the validity of the "affective prediction" model which offers a completely new perspective on vision-emotion interactions, by considering that these systems maintain close and early relationships in the continuum of cognitive processing .

Axe 2. Familiarity & Social InteractionsSense of familiarity is a crucial aspect of recognition because it provides the experience that an item, a person, has been previously encountered, independently of its identity or of any recollection of the associated details. This ability is essential to establish appropriate social interactions. Our recent work highlighted the importance of affective processes in familiarity access, particularly for specific familiarity (e.g. family, friends, personally known streets, places, own objects...). In this axis, we examine the mechanisms and neural correlates of perceptual, affective and cognitive processes involved in familiarity feeling. Moreover, to better circumscribe the impact of familiarity disorders on social interactions, we use a transdiagnostic approach, in disorders known to impact social interactions such as schizophrenia, alcohol dependence, depersonalization, autism-spectrum disorders... A second line of research focuses on early social interactions. This project is more particularly developed through the study of the relationship between post-partum depression (PPD) and mother-baby interactions. Indeed, PPD impacts mother-baby interactions and tuning abilities, which can result in mother-child bonding impairments. Maternal behavior is one aspect of social skills for which regulation by oxytocin (OTX) is particularly documented. The main aim of this second project is to test whether we can improve mother-baby interactions in mothers at-risk for PPD using intranasal OTX. Meta-analysis showing functional maps of the brain network activated during familiar faces presentation (from Horn et al., Cogn Affect Behav Neurosci 2016).
Axe 3. Brain plasticityBrain plasticity, defined as the ability of the nervous system to adapt to environmental demands, is crucial to the brain functioning and to its homeostasis. We use severe mental illness to study different aspects of brain plasticity. The first topic of this research axis is dedicated to the development of an objective psychiatry using computer science methods. The second topic focuses on a multi-scale approach to the environment (i.e. "everything different from the gene") in psychiatric disorders (genetics, imaging and epidemiology). Several projects are developed in this field, such as the epidemiology of environmental factors in severe mental illness, the multi-scale approach to physical treatments (neuromodulation) such as transcranial magnetic stimulation and electro-convulsive therapy, and pharmacogenetics coupled with imaging in the prediction of response to treatment. Finally, the last topic focuses on the recently developed concept of plastic adaptation to pathology, highlighting the bidirectional nature of the neuroplastic modifications associated with the longitudinal evolution of psychiatric disorders, particularly in the light of the concepts of brain economy.
Axe 4. Affective PredictionsProcessing the affective value of sensory information is an essential part of individuals' interactions with their environment. Impairment of this skill is a central component of many disorders in psychiatry and addiction. This line of research is therefore interested in the neurocognitive mechanisms underlying the reaction to or anticipation of affective stimuli using neuroscience (EEG, eye-tracking, electrodermal response…) and experimental psychology (visual stimuli and hearing, virtual reality...) methods. Our current work focuses more specifically on the perception of emotional and social signals and the allocation of attentional resources to these stimuli in alcohol use disorders and post-traumatic stress disorder. It also aims to offer new therapies dedicated to the management of these affective disorders. Illustration of the integrated model proposed in the context of severe alcohol use disorders. The model postulates that the difficulties of patients in visual perception are the result of the combination of bottom-up and top-down deficits, the latter being the cause of inappropriate predictions, including on the affective content of stimuli, early in sensory processing (adapted from Creupelandt et al., 2019).
