Condition	n(cells)	Variance	p Value of Comparison with
			Normal	Unoperated control side
Normal animals, full extent	54	664
Control side, full extent	29	940	0.272
Neonatal SC lesion, no superficial layers	75	3908	<<0.0001	<<0.0001

The results of F tests comparing the variances in the topography errors in equivalent portions of the SC. Based on the data shown in Figures 8 and 10.
