![(A) Schematic of experimental setup in the synchrotron beamline. The monochromatic X-ray beam impinges the thin section and photons are scattered at small angles according to their interactions with the sample’s nanostructure and captured by an area detector. (B) Principle of detecting (crossing) orientations: schematics (left side) and real data (right side) for single (upper panel) and crossing fibers (lower panel). The X-ray photons interact with the periodic myelin layers (left) and produce peaks in the resulting scattering pattern (middle). The radial position (distance from the pattern center, q) of the peak depends on the myelin layer periodicity d (q = 2π/d), while the azimuthal position depends on the axonal orientations (with photons being scattered at a plane perpendicular to the axon orientation, cf. Georgiadis et al. [22]). To extract exact axonal orientation, the azimuthal profile of the myelin signal across a ring (circumscribed by red dotted lines in the upper scattering pattern sketch) is plotted on the right. The peaks are subsequently identified using the <t>SLIX</t> <t>software</t> (Reuter and Menzel [32]). The position of the peaks in the x-axis (which are always 180° apart due to the center-symmetry of the pattern) reflects the fiber orientation angle. In the scattering patterns, the center area (where the direct, non-scattered beam lands on the detector) is covered by a beamstop that usually includes a photodiode. In addition, the real scattering patterns (middle right panels) have dark stripes (here in the up-down direction) corresponding to detector gaps that accommodate detector electronics. Moreover, the real scattering patterns include multiple orders of the myelin peak, with higher orders at lower intensities, as expected by Bragg’s law combined with the form factor of the myelin layer.](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_1447/pmc10811447/pmc10811447__nihms-1959019-f0001.jpg)

Figure Legend Snippet: (A) Crossing of two fiber bundles. Left panel: fiber orientations for each pixel encoded by the pixel’s color, with 4 quadrants per pixel encoding possible multiple orientations as explained in Section 2.3. Right panel: fiber orientations for each pixel are overlaid as colored bars on the azimuthally integrated intensity image, with possible multiple orientations resulting in overlaying bars. Orientation is color-encoded according to the color wheel. Inset: Photo of the fiber strips within the coverslips, with scanned area in red rectangle. (B) Azimuthal intensity profiles (azimuthal scattering intensity across the myelin peak, cf. Fig. 1) for pixels i, ii, and iii, indicated by circles in the right panel of (A). Plot outline colors correspond to the colors of the circles in (A). (C) Azimuthal profiles of 10 subsequent scan points highlighted by yellow rectangle in (A). Profiles show transition from two clearly separate peaks (points 1-2) to one merged peak (points 3-7) and back to two distinct peaks (points 8-10). Data indicate a minimal angle at which SAXS fiber crossings can be identified by the SLIX software of the order of 25-30°. (D) Crossing of three fiber bundles. Left Panel: fiber orientations for each pixel encoded in its color. Right panel: fiber orientations plotted as colored bars. Orientation is encoded by pixel color (left) or bar color (right) according to the color wheel. Inset: Photo of the fiber strips within the coverslips, with scanned area indicated by red rectangle. (E) Azimuthal profiles from select points in (D), with one (cyan), two (magenta), and three (orange & yellow) crossing fibers. As explained in the Methods section, in the colored fiber orientation maps (A), (D) each pixel is split into 4 quadrants, to accommodate 4 possible SLIX-derived fiber orientation colors. For pixels characterized by a single fiber orientation, all 4 quadrants have the same color. For pixels with two crossing fibers, the color of the diagonal quadrants indicates the respective fiber orientations. For pixels with three crossing fibers, 3 quadrants are colorized indicating the respective fiber orientation, while the 4th quadrant is black.
