Sagittal and horizontal section images showing neuronal nuclei, calbindin and parvalbumin staining in the rat hippocampal region

Bright-field microscopy images of serial sagittal and horizontal (half hemisphere) brain sections showing neuronal nuclei (NeuN), calbindin and parvalbumin in an adult male Long Evans rat (case 902). The images show the detailed architecture of this complex region and enable identification of regional and subregional boundaries.
