(A and E) Coronal sections through E14 control (A) and Nrg1 mutant (E) embryos showing nuclear staining and DiI labeling after dorsal thalamic (dTh) injections.
(B, C, F, and G) Higher magnifications of the internal capsule region (arrows) in control (B and C) and Nrg1 mutant (F and G) embryos.
(D and H) Schematic representation of the pathway taken by TCAs in control and Nrg1 mutant brains. GP, globus pallidus; Hyp, hypothalamus; Str, striatum. Scale bar = 300 μm (A and E) and 200 μm (B, C, F, and G).
