Robust Cable Models for Complex Neuronal Morphologies

MASCAF fits cable models to closed 3D surface mesh neuronal morphologies with cyclic topology, enabling robust modeling of barn owl auditory “toric spines” despite topological holes.

• Why it matters: Existing cable-fitting tools often assume acyclic structures, so they fail for neuroanatomically special non-tree morphologies like toric spines with loops and high curvature.
• What they did: The free, open-source, semi-automated MASCAF pipeline uses mean-curvature flow skeletonization to fit cable models to closed surface meshes and reconstruct loop connections for multicompartmental simulation.
• The result: The approach is validated with geometry and simulator-based methods, providing a deterministic, topologically robust workflow that bridges neuronal imaging and high-resolution simulation for general morphologies.
