Imagerie Chimique et Spéciation en Neurosciences

Chemical Imaging and Speciation in Neuroscience

Understanding the neurobiological and neurotoxic mechanisms of metals using spectroscopic imaging techniques.

ICS-Neuro

L’équipe ICS-Neuro développe et applique des méthodes d’imagerie chimique dans le domaine des neurosciences pour comprendre les fonctions neurophysiologiques des métaux et les effets neurotoxiques de contaminants inorganiques stables ou radioactifs.

The ICS-Neuro team develops and applies chemical imaging methods in the field of neuroscience to understand the neurophysiological functions of metals and the neurotoxic effects of stable or radioactive inorganic contaminants.

The main research themes of the ICS-Neuro team are:

  • Neurobiology of copper and zinc
  • Metals neurotoxicology
  • Iron and copper dyshomeostasis in neurodegenerative diseases
