Fig. 3: Tissue ultrastructure is preserved after SXRT.

Volumes obtained from the same sample: synchrotron X-ray CT (a) and posterior volume EM at high (10 × 10 × 40 nm3) resolution (b). Two regions of interest are cropped out to showcase the ultrastructure of the tissue. c Close-up details of the slices indicated in (b), displaying features indicative of well-preserved ultrastructure: axon bundles (yellow), thin dendrites (green) and synapses (red arrowheads). gl, glomerular layer; epl, external plexiform layer.
