abstract = {Understanding the cortical organization of the human brain
requires interpretable descriptors for distinct structural
and functional imaging data. 3D polarized light imaging
(3D-PLI) is an imaging modality for visualizing fiber
architecture in postmortem brains with high resolution that
also captures the presence of cell bodies, for example, to
identify hippocampal subfields. The rich texture in 3D-PLI
images, however, makes this modality particularly difficult
to analyze and best practices for characterizing
architectonic patterns still need to be established. In this
work, we demonstrate a novel method to analyze the regional
organization of the human hippocampus in 3D-PLI by combining
recent advances in unfolding methods with deep texture
features obtained using a self-supervised contrastive
learning approach. We identify clusters in the
representations that correspond well with classical
descriptions of hippocampal subfields, lending validity to
the developed methodology.},
