This is a toolbox and repository for open source mapping and contextualization of hippocampal data, paralleling surface-based mapping of the neocortex. This is partnered with a repository of mapped data at OSF.
See here for installation instructions, details on all tools provided, and tutorial walkthroughs.
HippoMaps provides tools for mapping data the folded and unfolded hippocampus are designed to work seamlessly with outputs generated by HippUnfold.
In the tutorials, we provide examples for mapping:
- laminar ex-vivo histology at the microscale
- structural MRI at 3T and 7T
- resting state fMRI properties and connectivity
- spatially scattered intracranial EEG (iEEG) recodings
- task-fMRI data mapping with nilearn
- comparison between maps and dimensionality reduction
These tutorials provide clear examples of how the tools here can be used, but for shorter examples and usage notes, see also demos.
Surfaces from Hippunfold version 2 are now supported and can be interpolated between version 1 ('0p5mm', '1mm', '2mm', 'unfoldiso') and 2 ('2k', '8k', '18k') densities using the density_interp function
