Evolution of Cajal’s drawings: Award-winning image shows neuroimaging progress in a century

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.”

About FENS:

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.”
