To reproduce the analyses presented in the referred study, in this repository you could find the MR images acquired from nine young healthy subjects (YS1-YS5), four elderly healthy subject (ES1-ES4) and two drug-resistant tremor patients treated treated with Vim radiosurgery by Gamma Knife (P1 and P2).

The provided dataset includes the following NifTI files:

- MPRRAGE @3T
- DWI @3T (together with the corresponding bvals and bvecs)
- MP2RAGE @7T
- SWI @7T
- binary masks of the manual delineation of both left and right Vim respectively that were done on the SWI (as NifTI files as well).

Additionally, for the young cohort (YS1-YS5) we include as well the images used for building the quadrilateral of Guiot:
- T2-w @3T
- T2 CISS @3T

For the patients (P1 and P2), a follow-up MPRAGE (acquired at 3T) with Gadolinium enhancement is also provided.

Notes:
1. For YS3 MP2RAGE at 7T is missing, instead MPRAGE at 3T was used

2. The code performing the thalamic nuclei clustering could be found in Zenodo (DOI: 10.5281/zenodo.123768)
