abstract = {Histological atlases of the cerebral cortex, such as those
made famous by Brodmann and von Economo, are invaluable for
understanding human brain microstructure and its
relationship with functional organization in the brain.
However, these existing atlases are limited to small numbers
of manually annotated samples from a single cerebral
hemisphere, measured from 2D histological sections. We
present the first whole-brain quantitative 3D laminar atlas
of the human cerebral cortex. It was derived from a 3D
histological atlas of the human brain at 20-micrometer
isotropic resolution (BigBrain), using a convolutional
neural network to segment, automatically, the cortical
layers in both hemispheres. Our approach overcomes many of
the historical challenges with measurement of histological
thickness in 2D, and the resultant laminar atlas provides an
unprecedented level of precision and detail. We utilized
this BigBrain cortical atlas to test whether previously
reported thickness gradients, as measured by MRI in sensory
and motor processing cortices, were present in a
histological atlas of cortical thickness and which cortical
layers were contributing to these gradients. Cortical
thickness increased across sensory processing hierarchies,
primarily driven by layers III, V, and VI. In contrast,
motor-frontal cortices showed the opposite pattern, with
decreases in total and pyramidal layer thickness from motor
to frontal association cortices. These findings illustrate
how this laminar atlas will provide a link between
single-neuron morphology, mesoscale cortical layering,
macroscopic cortical thickness, and, ultimately, functional
neuroanatomy.},
