SIGMA Rat Brain Templates and Atlases

Visit Website
The SIGMA resources offer to the preclinical neuroimaging community a complete set of in vivo and ex vivo templates, tissues priors as well as functional and anatomical atlases of the rat brain. SIGMA allows both linear and non-linear coregistration of multimodal acquisitions for accurate identification of the brain territories involved in physiological or pathophysiological conditions. Since March 1, 2024, a second version of the SIGMA resources is available and in this release we :
- updated the previous SIGMA spaces,
- revised the GM/WM segmentation and created additional probabilistic maps (outbrain, skull)
- created diffusion templates (B0, FA, etc.) at both ex-vivo and in-vivo resolutions.
- created a CT/18FDG reference space for multimodal normalization data
- delivered a new SIGMA brain atlas obtained by the normalization of the Waxholm space published by Kleven, H. et al. Nat Met. (2023)


Due to space limitation this second version is available here : https://zenodo.org/records/10730961

This work is part of the SIGMA project with the reference FCT-ANR/NEU-OSD/0258/2012, co-financed by the French public funding agency ANR (Agence Nationale pour la Recherche, APP Blanc International II 2012), the Portuguese FCT (Fundação para a Ciência e Tecnologia) and the Portuguese North Regional Operational Program (ON.2 – O Novo Norte) under the National Strategic Reference Framework (QREN), through the European Regional Development Fund (FEDER) as well as the Projecto Estratégico co-funded by FCT (PEst-C/SAU/LA0026-/2013) and the European Regional Development Fund COMPETE (FCOMP-01-0124-FEDER-037298). DAB and AN were funded by grants from FCT-ANR/NEU-OSD/0258/2012. RM was supported by the FCT fellowship grant with the reference PDE/BDE/113604/2015 from the PhDiHES program. AC was supported by a grant from the foundation NRJ. PM was funded by Fundação Calouste Gulbenkian (Portugal; 'Better mental health during ageing based on temporal prediction of individual brain ageing trajectories TEMPO') with Grant Number P-139977. France Life Imaging is acknowledged for its support in funding the NeuroSpin platform of preclinical MRI scanners. We acknowledge and thank Edward Ganz, MD, for proof reading our work
