Abstract: This dataset IF.iol contains the distinct intermediate orolateral fiber masses (iol) of the internal intermediate fiber masses of the amygdala (IF) in the individual, single subject template of the MNI Colin 27 as well as the MNI ICBM 152 2009c nonlinear asymmetric reference space. As part of the Julich-Brain cytoarchitectonic atlas, the intermediate orolateral fiber masses were identified on the basis of the topographic location of these fibers in relation to the cytoarchitectonic subdivisions of the amygdala in cell-body-stained histological sections of 10 human postmortem brains obtained from the body donor program of the University of Düsseldorf. The results of the analysis were then mapped to both reference spaces, where each voxel was assigned the probability to belong to IF.iol. The probability map of IF.iol is provided in the NifTi format for each brain reference space and hemisphere. The Julich-Brain atlas relies on a modular, flexible and adaptive framework containing workflows to create the probabilistic brain maps for these structures [Amunts et. al. 2020]. Note that methodological improvements and integration of new brain structures may lead to small deviations in earlier released datasets. Available coordinate spaces: • MNI ICBM 152 (2009c Nonlinear Asymmetric) • Colin 27 (1998, cropped) The map of fibers IF.iol is a part of the internal intermediate fiber masses of the amygdala (IF), which was also published as a probabilistic map of the Julich-Brain cytoarchitectonic Atlas. For technical reasons, this finer parcellation is only representable via individual probabilistic maps due to the spatial resolution of the reference space, i.e., there is no MPM available including fibers IF.iol.
