(A–F) Repeated imaging of the same dendritic branches over 4 days in the barrel cortex of wild-type and ephrin-A2 KO mice under control (A, B), deprived (C, D) and sensory enriched (E, F) conditions. Scale bar, 2 µm.
(G) Percentages of spines eliminated over 4 days in the barrel cortex (BC) under different conditions.
Data are presented as mean ± SD. *P<0.05, **P<0.01, ***P<0.001. See also Figure S3.
