Resources from our cortical auditory areas project that combines the gold-standard human histology images from JuBrain with state of the art in-vivo human magnetic resonance imaging (MRI) at ultra-high fields (7 Tesla). More specifically:

1. We use 10 individual brains with cytoarchitectonically labelled areas to create a surface atlas that is optimized for the human auditory cortex. This atlas is shared here as a resource for fellow researchers:

2. We make use of our atlas in combination with ultra-high field MRI to visualize the underlying in-vivo measurements such as myelination and tonotopy. This is done to exemplify a potential use case of our cytoarchitectonic atlas:

• Individual in-vivo 7T MRI data from:

• We created our surface atlas by incorporating anatomical priors into standard curvature based alignment pipeline as implemented in BrainVoyager 21.4. See this document for the steps involved.

• Since BrainVoyager is a commercial software which might not be available to all researchers, we share our resources here to help others implementing this method on their own. Feel free to ask questions on this repository's issues page.
