The use of stereotaxic brain templates in automatic neuroimage analysis has become the predominant technology. However, in the context of experiment studies involving cynomolgus monkeys, there is a lack of adequate brain templates. This gap poses a challenge to effectively utilize cynomolgus monkeys in neuroscience research. Considering the dynamic changes in structural morphology and functional maturity during development and aging, particularly post-birth, improving the accuracy of image data analysis necessitates the construction of a series of stereotaxic brain templates spanning all age groups. Therefore, this study developed a comprehensive set of stereotaxic templates for development cynomolgus brain with fine substructure delineations, including T1WI MRI structural template, tissue probability map (TPM), [
