Photomicrographs of labeled neurons in the CN following an injection of BDA into the contralateral GCD. The labeled CN-commissural neurons in VCN had round-to-oval somata (A, B, E, F, I), polygonal (D), or elongate somata (C, H), and had varied sizes. The labeled commissural neurons in DCN had round or elongated somata and were located in DCN3 (H, I). The occasional labeled CN-commissural cells in the SCC had polygonal somata (C, G). Scale bars = 50 μm.
