D1DRs (green, D1 dopamine antibody) are present in the lateral cerebellar nuclei −3.10 to −3.40 mm in the medial-lateral plane as identified using the Allen Rat Brain Atlas. Additionally, staining for tyrosine hydroxylase (a dopamine precursor, red) identifies axons of dopaminergic neurons likely originating in the VTA and/or the locus coeruleus. Outlined areas indicate putative subregions of sagittal sections through the cerebellar nuclei based on the Allen Rat Brain Atlas from −3.10 to −3.40 mm in the medial-lateral plane. These areas include: superior cerebellar peduncle (SCP), dorsal lateral hump of the interposed nuclei (DL interposed n.), lateral parvicellular, and lateral cerebellar nuclei (LCN).
