Histogram showing the percentage of area 9 pyramidal cell spines which contain label for D1, D5, DARPP-32, I-1, PP1α and PP1γ1 (previously published in Muly et al., 2001; Bordelon-Glausier et al., 2008). For DARPP-32, 134 micrographs containing 644 spines were analyzed, and 135 micrographs containing 624 spines were analyzed for I-1. The percentage of spines labeled by DARPP-32 (4.4% ± 0.938%) and I-1 (7.7%) ± 1.25%) was significantly less than the percentage labeled for D1, D5, PP1α and PP1γ1 (F5,979 = 164.333, p < 0.0001).
