One week of late juvenile visual experience prevents deprivation-induced RF enlargement in adulthood. (A) Experimental design. Conventions as in Figure 1. (B) Effect of a brief period of normal light cycle from P33 to 40 or P37 to 40 on DR-induced RF enlargement. The P33–40 light group had RFs that were normal in width. However, the P37–40 light group had significantly enlarged RFs (*P < 0.05, compared with P90 Normal). Data are presented as median ± IQR. (C) Cumulative probability plots showing the distribution of data in B. Note that the difference between groups is due to an increased proportion of large RFs.
