(A) Cumulative distribution of ΔO for simple cells in
five age groups during development: P15–18, P20/21, P22/23, P26/27,
P31–36. (B) Mean ΔO of simple cells is high at
P15–18 and P20/21, similar to the dark-reared (DR) mice, then decreases
and reaches the mature level by P22/23. (C) Mean OSI of simple cells increases
during development for both contralateral (P15–18 vs. P31–36, P
< 0.05) and ipsilateral (P15–18 vs. P31–36, P = 0.06;
P20/21 vs. P31–36, P < 0.001) eyes. (D) Cumulative distribution of
ΔO for complex cells in all five age groups during
development. (E) Mean ΔO of complex cells is high from
P15 to P27, very similar to the DR group. It decreases after P27 and reaches
mature level by P31–36. (F) Mean OSI of complex cells remains similar
during development for both contralateral (P15–18 vs. P31–36, P
= 0.79) and ipsilateral (P15–18 vs. P31–36, P =
0.50) eyes. Error bars represent mean ± SEM (*p < 0.05,
**p < 0.01, ***p < 0.001). See
