Probabilistic fibre tract analysis of cytoarchitectonically defined human inferior parietal lobule areas reveals similarities to macaques

► Human inferior parietal connections to 64 targets using probabilistic tractography. ► Implementation of analysis algorithm for quantitative evaluation of connections. ► Accounting for seed size and distance between seed and target areas. ► Gradual shift of connection patterns from rostral to caudal IPL. ► Left-right asymmetry of connections for different functional systems.
