Brain parcellation¶
The purpose of this project is to derive algorithms that parcellate the brain into functionally homogeneous regions. These regions will then be candidates for further functional cross-subject alignment.
Demo-parcellation of the left hemisphere in functionally defined ROIs. Each ROI is defined by a unique set of participating tensor-ICA component maps. These components were derived from an fMRI dataset consisting of 10 subject s the saw half of the movie “Raiders of the lost ark” while being scanned. The figure panels show a (A) lateral, (B) medial, (C) dorsal, and (D) ventral view of the cortex surface. Each color indicates a contiguous ROI
Notes¶
Subjects cb00 and ph00 in the Princeton movie dataset were excluded from further analysis due to excessive “spiky” motion with jumps of more than 2mm displacement. That had a significant impact on the outlier modeling behavior of the extracted ICs.
