|I am professor of Cognitive Science at Aix-Marseille Université (AMU) since 2001 in the “Body and Cognition” team of the “Adaptive and Integrative Neurosciences Lab” – where I devoted much of my time to develop and test brain training tools for cognitively impaired patients (such as Alzheimer or Cranial Trauma). I received numerous honors (including the 2008 Innovation National Prize of the National Intellectual Property Institute) for this work. I was an invited researcher at CESAR-ORNL, USA, 1997-1999) working on the learning of cooperation for a group of robots. My (Computer Science) doctorate thesis subject (1990) was on learning sequences with artificial neural networks. I also hold a Master Degree in Neurosciences (1985).
The “Body & Cognition” team focus its research on the inter-actions between the cognitive and sensory-motor functions at various organizational levels (multi-sensory bases of cognitive representations of the body and space, cognitive and neurobiological mechanisms associated to cerebral dysfunction and cognitive restoration, cognitive influences over sensory and motor processes, aging and clinical applications), combining plural-disciplinary approaches (behavior, neuroimaging, neurophysiology, neurology, oto-neurology, modelization and simulation).

In 2014, I published a second volume related to the Theory of neural Cognition. This theory synthesizes and resumes my research activities of the last 25 years. The Theory of neural Cognition (TnC) claims that our brain does not process information, but represents information – we are only a crystallization of our interactions with the environment. TnC explains how each and every one of our cognitive abilities is implemented by, or through, a set of cortical maps – including consciousness. Since TnC refers explicitly to the eliminative materialism paradigm, these explanations – despite being quite simple – are neither popular, nor widespread.
