Figure 7.
Histogram showing the percentage of area 9 axon terminals which contain label for D1, D5, DARPP-32 and I-1 (previously published in Muly et al., 2001; Bordelon-Glausier et al., 2008). For DARPP-32, 134 micrographs containing 1,121 terminals were analyzed, and 135 micrographs containing 1,145 terminals were analyzed for I-1. The percentage of terminals labeled by DARPP-32 (3.7% ± 0.69%) and I-1 (5.9% ± 0.78%) was significantly less than the percentage labeled for D1, but not D5 (F3,795 = 22.429, p = 0.0001).
