About the Image:
“With this image I want to illustrate the large advances made in imaging methods over the past century, allowing modern neuroscientists to look at neurons in ways that Cajal could have only dreamed of. The composition was created by mirroring an image of two pyramidal cells of a mouse hippocampus.
Using the technique of single-cell electroporation, the DNAs encoding a fluorescent protein and an opsin fused to a different fluorescent protein were introduced in these neurons. The left image shows opsin fluorescence intensity as inverted gray values to create a Cajal’s drawing-like appearance. In the right image the fluorescence protein is shown in blue and the opsin is shown in orange.”

FENS, the Federation of European Neuroscience Societies, is the voice of European neuroscience, representing more than 20,000 European neuroscientists.
The FENS-EJN Image Competition was held for the first time in 2020. Over 80 images were submitted, from a wide range of topics. Congratulations to Silvia Rodriguez-Rozada (Centre for Molecular Neurobiology Hamburg, Germany), for her image “Evolution of Cajal’s drawings.”
