Diffuse terminals throughout sgs
Rostral	0.27 ± 0.07	3.41 ± 1.76*	3.27 ± 1.70*
Medial	0.43 ± 0.25	2.41 ± 0.49*	2.01 ± 0.34*

Values are means ± SEM for each genotype. The density of ipsilateral terminals is shown for the dense patches of terminal clusters (appropriate distribution) as well as for the diffuse terminals observed in ephrin-A^−/− mice (inappropriate distribution). The density of diffuse terminals is shown separately for the rostral, medial, and caudal SC. Values in rostral and medial SC in WT are not significantly above background.

*Values are significantly different compared with WT.
