Stanislas Dehaene is a Full Professor in the Chair of Experimental Cognitive Psychology at the Collège de France in Paris. He completed a Ph.D. in Cognitive Psychology at the Ecole des Hautes Etudes en Sciences Sociales, Paris. He heads the Cognitive NeuroImaging Unit at NeuroSpin on the Commissariat A l Energie Atomique campus in Saclay near Paris. Stanislas Dehaenes interests focus on the cerebral bases of specifically human cognitive functions such as language, calculation, and conscious reasoning. His team uses a variety of experimental methods, including mental chronometry in normal subjects, cognitive analyses of brain-lesioned patients, and brain-imaging studies with positron emission tomography, functional magnetic resonance imaging, and high-density recordings of event-related potentials. Formal models of minimal neuronal networks are also devised and simulated in an attempt to throw some links between molecular, physiological, imaging, and behavioral data.
