It's once again Friday at @institutpasteur.bsky.social !!!

yes, that's what we meant. We often use as example a bow setting a Chladni plate into vibration. The patterns require the bow to appear, but are not encoded in the bow. Similarly, unspecific genetic control of growth is required, but it doesn't encode the neuroanatomical/behavioural outcome

as @aitormg.bsky.social mentioned, the slicing process introduces some nasty deformations. Depending on the geometry of the brain, and the direction of the blade, there's local scaling and skew. Here I find a 12 dof affine that takes each raw slice to the same slice after (global) Laplace smoothing:

and with the uniform Laplacian we get a quite funny artefact! (most likely due to the straight cut from the midbrain, which has a few very large triangles)

here's the result with the cotan Laplacian (quite nice!)
