Distribution of calbindin-positive neurons in the developing mouse brain (v3)

This dataset contains high-resolution images of coronal sections showing calbindin-expressing neurons across the developing mouse brain. A total of 44 mice aged postnatal day (P) 9, 14, 21 and 35 were used in this study. Calbindin was visualized in every sixth section using DAB immunohistochemistry with a monoclonal mouse anti calbindin antibody (RRID:AB1000347). Neighboring sections from the same subjects stained for parvalbumin are available from a separate dataset [(Bjerke et al., 2026a)](https://doi.org/10.25493/F3F9-Z11). The data can be used to investigate the developmental trajectory of calbindin neurons in the mouse brain, and may be compared to our previously published data from adult [(Bjerke et al., 2026b)](https://doi.org/https://doi.org/10.25493/J4S8-A84) acquired using the same techniques.
