The neurological and psychiatric effects of SARS-CoV2, including Long Covid, have again highlighted - if need be- the potential importance of pathogens (considered as -not primarily- neurotropic) for the health of the nervous system. A feature which was confirmed by the remarkable recent publication (January 2022, in Science) of a key role of the Epstein Barr Virus in Multiple Sclerosis, a hypothesis that was raised for years, but very difficult to demonstrate (Bjornevik et al., 2022). Beyond its impact on neuroscience and other disciplines, Covid19 will have also influenced -probably in the long term- our way of working together. Virtual meetings and lectures, despite constituting an obvious decrease in socialization, have allowed to maintain some dynamic of scientific interactions. Because this may participate -at least partially- in increased convenience, outreach and usability (especially with regard to geographically remote guests), a much larger proportion of workshops and meetings now have a hybrid (face-to-face & virtual) format, in our network but also worldwide. Regardless of the difficulties, our network continued to develop: the Neurex universities have recruited new team leaders during the pandemic. We are pleased to introduce some of them in this newsletter and will go on in the next ones: welcome to them! Scientific events are gradually coming back to normal. Be it by zoom or in real, we hope to see many of you there as before the pandemic!
