Labeling in the telencephalon of E12.5 embryos after DiI injections in the cortical wall (cx).A, Cortical fibers end with complex growth cones in the lateral part of the GE. A very small number of fibers extend in the medial part of the GE. Dotted lines indicate the outlines of the section, and the star indicates the ventricular angle.B, C, Retrogradely labeled cells observed in the mantle of the GE, near the front of growth of efferent cortical fibers. The focus was changed between the two plates, and arrows show the same cell. Scale bars: A, 200 μm; B, C, 50 μm.
