The Human Connectome

The human connectome is a detailed description of the functional and structural connectivities between all cortical areas and subcortical structures in the human brain. The INM-1 aims for a multi-modal and multi-scale brain model, which respresents the basis for any kind of network analysis and simulation.
The team „Connectome“ develops a novel neuroimaging technique (3D-Polarized Light Imaging, 3D-PLI) to map nerve fibers and their pathways in white and gray matter of the human postmortem brain with a resolution at the sub-millimeter scale. The basic idea is to apply fundamental principles of polarizing imaging in different optical setups, thus providing complementary scales of resolution to bridge the gap between structural descriptions of the human connectome at single fiber dimensions and at macroscopic fiber pathway levels. The team is in charge of developing experimental setups as well as the corresponding methods for signal analysis and interpretation.
