A detailed study using time-resolved spectroscopy conducted at the Iramis reveals the mechanisms associated with these processes.

An international consortium, of which IRAMIS is a member, was able to identify five of these forms by combining computer simulations of quantum chemistry and UV photonization imaging carried out at the SOLEIL synchrotron facility.

INSERM and CEA researchers recently showed that the pharmacological blocking of the TGFβ molecule improves the production of new neurons in the mouse model.
