Patterned expression in the caudoputamen. (a) Gradient (Equation 3) and (b) patterning (Equation 4) scores were computed across five rostrocaudal caudoputamen bins (rainbow) for all ABA 3D expression profiles. In situ images and caudoputamen voxel calls (inset) are shown for two genes with graded expression: (c) rostrally enriched sodium–calcium exchanger NCX3 isoform (Slc8a3; gradient = −0.84; ABA image 72577486) and (d) caudally enriched Ras-specific guanine nucleotide-releasing factor 2 (Rasgrf2; gradient = 0.94; ABA image 69791544).
