A way to better appreciate the ancient or evolved Homo sapiens brain characteristics relies on comparative investigations with homologous species. Chimpanzees remain our closest living hominid relatives, making it a pertinent model for brain studies. Few investigations address the structural connectivity of the chimpanzee brain, whereas its proximity with humans could be key to understanding the human brain. Thanks to the unique imaging data collection provided by the National Yerkes Primate Research Center and the access to elaborated diffusion MRI tools to investigate brain connectivity, we propose a novel long bundle atlas of the white matter of the chimpanzee brain.
