On page 3 of the PDF and print version of this Letter, column two, in the text describing the mEPSC frequency and dendritic spine density values shown in Fig. 3b and 3c, the words 'saline' and 'cno' were erroneously exchanged. The correct text should read: (D1-Cre, direct pathway MSNs: frequency, saline 0.8 ±0.1 Hz, n = 18; cno 0.36 ± 0.07 Hz, n = 25; spine density, saline 0.96 ± 0.04 spines per um, n = 5; cno 0.49 ± 0.05 spines per um, n = 5; D2-Cre, indirect pathway MSNs: frequency, saline 0.04 ± 0.01 Hz, n = 7; cno, 0.27 ± 0.09 Hz, n = 8; spine density, saline 0.54 ± 0.05 spines per urn, n = 5; cno 0.98 ± 0.06 spines per um, n = 5). This has been corrected online in the PDF and HTML of the original paper.
