It is with great sadness that we share news of the passing of Deborah Levy. Since 2015, Debbie had been a member of IPNP international Scientific Advisory Board. She participated in every single evaluation during the last five years, including 3 open calls and the evaluation of our 2019-2024 plan. During this time, Debbie befriended many IPNP scientists. We benefitted not only from her intelligence and scientific insight, but also enjoyed her humor and warmth. The entire iSAB and IPNP community mourn...

Loss of Olfactory Function—Early Indicator for Covid-19, Other Viral Infections and Neurodegenerative Disorders. Rebholz H, Braun RF, Ladage D, Knoll W, Kleber C, Hassel AW. Front. Neurol., 26 October 2020 | https://doi.org/10.3389/fneur.2020.569333 Download from HAL-INSERM The loss of the senses of smell (anosmia) and taste (ageusia) are rather common disorders, affecting up to 20% of the adult population. Yet, this condition has not received the attention it deserves, most probably because...

How Do Electric Fields Coordinate Neuronal Migration and Maturation in the Developing Cortex? Medvedeva, V, Pierani, A. Front. Cell Dev. Biol. 2020 Sep 8: 1006.doi:10.3389/fcell.2020.580657 Download from HAL-INSERM : https://www.hal.inserm.fr/inserm-02973314 During development the vast majority of cells that will later compose the mature cerebral cortex undergo extensive migration to reach their final position. In addition to intrinsically distinct migratory behaviors, cells encounter and...

Myelination of parvalbumin interneurons shapes the function of cortical sensory inhibitory circuits. Benamer N, Vidal M, Balia M, Angulo MC. Nat Commun 11, 5151 (2020). https://doi.org/10.1038/s41467-020-18984-7 Abstract Myelination of projection neurons by oligodendrocytes is key to optimize action potential conduction over long distances. However, a large fraction of myelin enwraps the axons of parvalbumin-positive fast-spiking interneurons (FSI), exclusively involved in local cortical circuits....

Role of the Sec22b-E-Syt complex in neurite growth and ramification. Gallo A, Danglot L, Giordano F, Hewlett B, Binz T, Vannier C, Galli T. J Cell Sci. 2020 Sep 15;133(18):jcs247148. doi: 10.1242/jcs.247148. PMID: 32843578. Download from HAL-INSERM Abstract Axons and dendrites are long and often ramified neurites that need particularly intense plasma membrane (PM) expansion during the development of the nervous system. Neurite growth depends on non-fusogenic Sec22b-Stx1 SNARE complexes at...
