For #SciArtSeptember: 50 EPG neurons from the #Drosophila, segmented from electron microscopy images, rendered in #Blender3d driven by neuVid. This ring of neurons forms part of the fly’s internal compass. As the fly changes its heading, neuronal activity moves around the ring, as shown by the false color gradient. Imaging and reconstruction by #HHMIJanelia and Google Research (www.janelia.org/project-team/flyem/hemibrain); function described by Hulse et al (doi.org/10.7554/eLife.66039).
