Higher magnification LCIC expression of ephrin-B2 (A) EphA4 (B) and ephrin-B3 (C) at P8. Ephrin-B2 and EphA4 expression includes somata and neuropil labeling that is most heavily concentrated within periodic, discontinuous presumptive modular fields (A, B, dashed contours). In contrast, ephrin-B3 labeling is low in presumptive modular zones (C, dashed contours) and more uniformly distributed in surrounding extramodular domains. Scale bars = 50 μm.
