National initiatives
DGE Ministry grant COMAC “Optimized multitechnique control of aeronautic composite structures”
Participants : Laurent Bougrain, Octave Boussaton, Marie Tonnelier.
The goal of this three-years project is to develop a powerful system of control on site, in production and in exploitation, of aeronautical pieces made of composite. It takes up the challenge of the precise, fast and local inspection on composite pieces of aeronautical structures new or in service by using techniques of non-destructive control more effective and faster to increase the lifespans of the structures of planes. This project requires a decision-making system including fast methods of diagnostic based on several optical technics as non-destructive control.
INRIA ADT project LOIC
Participants : Laurent Bougrain, Baptiste Payan.
This national software collaborative project with the INRIA research team BUNRAKU (Rennes) is devoted to OpenViBE (cf. § 5.4 ). The objectives of the project are:
ANR project KEOPS
Participants : Frédéric Alexandre, Laurent Bougrain, Thierry Viéville.
This «ANR International White Project» involving NEUROMATHCOMP and CORTEX Inria EPI in France with the U. of Valparaiso, U. Tecnica Frederico Santa-Maria, and U. De Chili is a 3 years, 248 person-months, sensory biology, mathematical modeling, computational neuroscience and computer vision, project addressing the integration of non-standard behaviors from retinal neural sensors, dynamically rich, sparse and robust observed in natural conditions, into neural coding models and their translation into real, highly non-linear, bio-engineering artificial solutions. An interdisciplinary platform for translation from neuroscience into bioengineering will seek convergence from experimental and analytical models, with a fine articulation between biologically inspired computation and nervous systems neural signal processing (coding / decoding).
ANR project PHEROTAXIS
Participants : Dominique Martinez, Thomas Voegtlin.
How can animals so successfully locate odour sources? This apparently innocuous question reveals on analysis unexpectedly deep issues concerning our understanding of the physical and biological world and offers interesting prospects for future applications. Pherotaxis focuses on communication by sex pheromones in moths. The main aim of the project is to integrate the abundant experimental data on the pheromone plumes, neural networks and search behaviour available in the literature, as well as that collected or being collected by us at the molecular, cellular, systemic and behavioural levels into a comprehensive global model of the pheromonal olfactory processes. To reach this objective, the consortium combines several groups of specialists with different and complementary fields, in physics (Institut Pasteur IP), neurobiology (INRA) and bio-robotics (INRIA).
ANR project PHEROSYS
Participants : Dominique Martinez, Hana Belmabrouk.
This collaborative project in systems Biology (ANR-BBSRC SysBio) with INRA (Paris, FR) and the University of Sussex (UK) explores olfactory coding in the insect pheromone pathway through models and experiments. More information available at http://www.informatics.sussex.ac.uk/research/projects/PheroSys/index.php/ .
ANR project MAPS
Participants : Frédéric Alexandre, Yann Boniface, Nicolas Rougier, Wahiba Taouali, Thierry Viéville.
This collaborative project with INCM (Marseille), UMR Perception and Movement (Marseille) and LIRIS (Lyon) that finished this year aimed at re-examining the relationship between structure and function in the brain, taking into account the topological (spatial aspects) and hodological (connectivity) constraints of the neuronal substrate. Particularly, we focused on the oculomotor function and explored the dynamical and topological representation of information in the superior colliculus.
Project of the CNRS NeuroInformatics program on cortical signals to control a two-finger robotic hand (CorticoRobot)
Participants : Laurent Bougrain, Thierry Viéville.
Nowadays, the understanding of the control of manual dexterity in primates can be reached. Over the last twenty years, thanks to improved techniques for intra-cranial recordings, several advances have been obtained in particular to predict the direction of movement of the upper limb. Recent work has shown that it is possible to predict from brain data the flexion and the strength of fingers. The main objective of this project is to study the control of two anthropomorphic fingers (index finger and thumb) through intra-cortical signals recorded in the monkey during grasping movements (precision grip), forecasting both the finger position and the electromyographic activity (EMG) of the muscles involved in the movements of these two fingers. The project aims at (i) acquiring high-quality recordings using an array of 96 micro-electrodes, (ii) improving our experimental site for the grasping, and (iii) evaluating new modelings. This project is a cooperation between the University of Paris V, the Mediterranean Institute for Cognitive Neuroscience (INCM) and the EPI CORTEX.
Project CNRS PEPII: A large-scale, robotically embodied decision making model
Participants : Frédéric Alexandre, Nicolas Rougier, Thierry Viéville.
This project is a collaboration between the “Institut des Maladies neuro-dégénératives” (UMR 5293, team “Approche systémique de la Boucle Extrapyramidale”), Supélec (“Information, Multimodalité, Signal”) and the Cortex team. This project aims at studying the decision making process viewed as a high-level brain function, actioned by a distributed network of cortical and sub-cortical structures, interconnected in positive and negative feedback loops.
Project CNRS PEPII IMAVO
Participants : Nicolas Rougier, Yann Boniface.
This project is a collaboration between the “Institut des Neurosciences Cognitives et Intégratives d'Aquitaine” (UMR 5287), the “Institut des Systèmes Intelligents et de Robotique” (Systèmes Intégrés Mobiles et Autonomes) and the LORIA (Maia and Cortex groups). This project aims at investigating model-free and model-based approaches in the decision process in order to propose a computational model of the decision process in simple tasks.
Project of the CNRS NeuroInformatics program on oscillations in the rat olfactory bulb
Participants : Axel Hutt, Dominique Martinez, Thomas Voegtlin.
This project is a collaboration between the CORTEX group and the "Neurosciences et Systèmes sensoriels" group (CNRS UMR 5020) at University of Lyon 1. The goal of the project is to understand why the frequency of LFP oscillations in the olfactory bulb changes during the respiratory cycle (alternance beta/gamma). The project combines experimental (in-vivo experiments) and theoretical work (computer simulations).
Project INRA-INRIA
Participants : Dominique Martinez, Thomas Voegtlin.
This project is a collaboration between the CORTEX group at INRIA and the PISC group at INRA. This project aims at reconstructing and explaining the encoding of the pheromone stimulus in the early neural pathway of the moth olfactory system. Models of single neurons based on Hodgkin-Huxley formalism are being developed to incorporate the ionic conductances found in experiments and to account for the overall properties of the cells. A network model is also built to account for the different response types in the moth olfactory system with respect to the temporal structure of the stimulus. The simulations are performed with the Sirene and Mvaspike softwares developed in our group.
