Neuroinformatique project Sensory transduction to Perception (2009-2010)

Project title

Analysis and Modeling of Sensory Transduction to Perception based on experimental data and neural network models

Project goals

How the interplay between sensory receptors and their primary interneurons becomes a perception is largely unclear, yet it represents an important step in sensory coding and perception. The codification of sensory information-the steps from sensory transduction to processing in the brain- displays great similarity in its principles and underlying elements between the senses. This proposal aims at understanding the role of distributed neuronal network activity in sensory perception in vertebrates including human beings, using physiological to formal neural network approaches. An integrative approach of researchers from different areas to the common problems of sensory transduction, transmission, and codification should yield significant synergy, and bring us closer to the ultimate goal of a full and detailed comprehension of our senses. Three sub-projects will be integrated to achieve our goal, and will be the pillars of this endeavor:

  • Artificial Sensory Neural Network and Brain Modeling (collaboration of all parters)
  • Parametric estimation of spike train statistics (collaboration of Nancy, Nice and Valparaiso)
  • Neuronal Network Mechanisms Underlying Sensory Coding in the Human Brain (collaboration of Nancy and Santiago de Chile)
