Just wondering how the nomenclatures available for the Ewert atlas differed? It seems that the structures on the Ewert atlas did not change but the labels for the structures are different and I am not sure how the atlas accounts for the different histological results?
Hi there, I don’t really understand what your question is.
The nifti files in the DISTAL (Ewert 2017) folder that have numbers (1.nii.gz etc.) follow the nomenclature of
Chakravarty, M. M., Bertrand, G., Hodge, C. P., Sadikot, A. F., & Collins, D. L. (2006). The creation of a brain atlas for image guided neurosurgery using serial histological data. NeuroImage, 30(2), 359–376. http://doi.org/10.1016/j.neuroimage.2005.09.041
But are also reproduced in the Ewert paper’s supplement.
Sorry for the confusion. In the 3D rendering of the Ewert atlas on Lead-DBS, there are labeling options of different nomenclatures like Hirai and Jones, but the name of a structure in the Ewert atlas is different depending on which nomenclature is used. For example 26.nii.gz is labeled differently depending on which nomenclature is used. Does that mean that these different nomenclatures have the same structures as the Ewert atlas but just labeled them different names? I am confused as to how different nomenclatures can be used with the Ewert atlas when each nomenclature is uniquely defined based on histochemical staining done on specific brain sections.
Gotcha, well, different thalamic nomenclatures still correspond to each other and an experienced neuroanatomist made these translations in the chakravarty paper (again see the same reference for more info on that). We adopted the dataset to complement the primary regions of interest (STN, GPi, GPe and RN) of the DISTAL atlas.
