Convergently evolved arcuate fasciculus in marmosets with humans

White matter connections coordinate functional brain activity by interconnecting various brain regions, weaving together a complex pattern with functional specializations refined throughout ontogeny and phylogeny (Thiebaut de Schotten & Forkel, 2022). Comparative analysis of white matter connections including a broader range of species could provide valuable insights into the mechanisms involved in human-specific cognitive functions. As a highly vocal Platyrrhine monkey that shares key anatomical and functional features with humans, marmosets provide a unique opportunity to chart white matter tracts for investigating brain evolution in the primate lineage.
