A consensus protocol for functional connectivity analysis: Dr. Marcelo Febo and AMRIS staff collaborated with a consortium of facilities to develop best practices for collecting high quality preclinical fMRI data. The lead author, Dr. Joanes Grandjean, is an Assistant Professor at the Donders Institute which is part of Radboud University in the Netherlands. He is the primary driver of these international standardization efforts for fMRI in rodents. These protocols are available on our 11 T system and will be available on our 7 T system in the coming weeks.
