Addiction, interoception and sex differences (NEED)

For decades, neurosciences research was exclusively on males with the assumption that biological processes are the same across sexes. This dogma created a huge gap in our understanding of behavioral and brain mechanisms in both sexes. Although the field proved that this dogma is not always true, it left an important question unanswered: Why males and females have different vulnerability to brain disorders? Drug addiction is among the disorders with the highest men/women prevalence ratio. While the prevalence is higher in men, the gap between men and women is narrowing highlighting that drug addiction affects both sexes. Clinical and preclinical…

Hybrid sensorimotor performance

Our team uses hybrid systems, which mix biological control with artificial devices, in order to (i) increase our understanding of sensorimotor control and (ii) exploit this knowledge to restore and optimize movement. Instead of being pre-programmed in the brain, movement coordination largely depends upon multiple feedback loops that operate at different levels of the sensorimotor control system. For instance, muscle mechanics provides an instantaneous functional response to small perturbations, while segmental and transcortical reflexes are able to absorb increasingly larger perturbations by precisely coordinating muscle responses for the complex musculoskeletal design of our limbs. These loops are typically violated in…

Psychobiology of drug addiction

Our team works at the understanding of the psychobiological mechanisms of addiction, notably to cocaine and tobacco. Drug use can lead to behavioral disorders of which an extreme version is addiction. This psychopathology is not a mere excessive drug use, but is defined as a loss of control over use, which is particularly reflected in the maintenance of use despite its adverse effects. Critically, all users are not equally at risk for addiction, however. Our experimental strategy consists in integrating these characteristics of the pathology, i.e. loss of control over drug use and individual vulnerability, for an increased face and…

More specifically, daily life evaluations unravel the intra-individual variability of physiological and cognitive functioning; we attempt to understand its anatomical and functional bases by analysing it…

Spatio-temporal and mechanical control of motile structures

Our goal is to decipher at the molecular level the spatiotemporal and mechanical mechanisms which control the architecture and dynamics of motile structures. First in the context of cell migration by studying integrin-based adhesion sites and the actin-based lamellipodium. Second in the context of neuronal structural plasticity by studying the actin cytoskeleton in axons and dendritic spines. Exploration of these new dimensions requires an innovative and multidisciplinary approach combining cell biology, biophysics, biomechanics and advanced optical microscopy techniques including super-resolution microscopy, single protein tracking and quantitative image analysis. Innovative techniques: single molecule localization microscopy (PALM, STORM, uPAINT), super-resolution microscopy (RESOLFT),…

Structural biology and engineering of neuronal signalling

The interests of our team lay at the interface of structural biology, protein engineering, and cellular neuroscience. We aim to understand molecular principles of neuronal signalling in health and disease, and to translate these to the cellular and organismal level. We use mammalian protein expression, protein chemistry, biophysical methods, X-ray crystallography and cryo-electron microscopy to study the interaction determinants and structures of synaptic protein complexes involved in neurodevelopmental disorders and neuronal disease. We use combinatorial methods and protein engineering to discover novel binders and manipulate protein sequence, structure and function, both to facilitate structural studies as well as enable therapeutic…

Synapse in cognition

Our main objective is to understand the link between synapse and cognition at the synaptic and circuit level. Our recent results show that several mental retardation (MR) mouse models exhibit functional synaptic deficits at cortical projections to the lateral amygdala (LA), a structure involved in the coding of fear memory. We will examine the role of MR proteins in the process of memory formation by analysing biochemical, morphological and physiological changes of cortico-LA synapses in mice submitted to fear conditioning. Innovative techniques: In vivo electrophysiology, in vivo two-photon imaging of neuronal activity, fluorescence-activated sorting of synaptosomes

Synapses and neural circuits in behaviour

The research carried out in our group ambitions to link cell biological mechanisms of proteins and lipids involved in glutamatergic synaptic function and dysfunction. Much of our work has focused on the roles of kainate receptors, a subject in which the group is internationally recognised. We elucidated new biophysical and pharmacological properties of kainate receptors in the developing hippocampal circuits and in temporal lobe epilepsy. Our group has also broken new ground with highly original work on the role of prostaglandins and other lipids in synaptic plasticity. Great efforts are made to develop new methods for investigating the connectivity and…

Synaptic plasticity and super-resolution microscopy

Our group objective is to better understand higher brain function and disorders through innovative and advanced technological developments. To this end, we are applying novel superresolution microscopy approaches (STED microscopy), giving us a much more complete and refined view of the dynamic behavior and plasticity of neuronal synapses and their interactions with glia cells inside living brain slices. This approach is complemented by a combination of 2-photon imaging and patch-clamp electrophysiology to address the underlying synaptic mechanisms of plasticity in the mammalian brain. Innovative techniques: STED microscopy in brain slices and in vivo, two-photon microscopy, glutamate uncaging, calcium imaging, biophysical…


The pathological aggregation of neuronal proteins is a key and often causal event in many neurodegenerative diseases. Synucleinopathy, characterized by the accumulation and spread of aggregated amyloid forms of alpha-synuclein in the brain, is observed in Parkinson’s disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies. Understanding the molecular mechanisms involved in the amyloid self-assembly of this small synaptic protein, tracking the cellular processes by which neurons handle its pathogenic conformational changes and deciphering the inter-neuronal propagation pathways of these aggregated forms are crucial aspects in neurodegenerative research and hold significant interest for therapeutic development. It is now…

Translational research in neurogenetic diseases (NRGEN)

The team gathers together researchers interested in a continuum of overlapping neurogenetic disorders covering spinocerebellar degenerations (ataxias, spastic paraplegias), motor neuron diseases (amyotrophic lateral sclerosis, hereditary spastic paraplegias, neuropathies) and neurodegeneration with brain iron accumulations (NBIA). Our goal is to dissect the molecular bases of these neurogenetic diseases with the long-term goal of developing specific therapies, which are lacking for almost all of them. To this end, we use a combination of genetic analyses (exome, genome, repeat expansion detection), phenotype-genotype correlations, biomarker searches and functional analyses (cellular, yeast and mouse models).
