Fig. 1.

Topographic retino-collicular projections in WT and Isl2-EphA3KI animals. Micrographs illustrate nasal 1,1′-dioctadecyl-3,3,3′3′-tetramethylindocarbocyanine perchlorate (Dil) injections in P8 retinas and the corresponding termination zone(s) in the SC. Top an injection in nasal WT retina leads to a single caudal termination zone in the SC. Middle an injection in a nasal EphA3KI/+ retina leads to two caudal termination zones in the SC. Bottom an injection in a nasal EphA3KI/KI retina leads to two distant termination zones in the SC. Scale bars 1 mm
