This work aims to describe the evolution of the three pairs of cerebellar peduncles (CP): superior (SCP), middle (MCP), and inferior (ICP) in 62 apparently healthy developing human subjects ranging from 30 gestational weeks (GW) to 28 years (Y) old, using high angular resolution diffusion imaging (HARDI) tractography. For the MCP, two dissociated pathways were considered: 1) pathways from the rostral pons to the inferior cerebellum (MCP-1) and 2) pathways from the caudal pons to the superior cerebellum (MCP-2).
