Fig 10. CB₁-R labeling in the membrane of the RGS9-Cre:ChR2-tdTomato and GAD-Cre;ChR2-tdTomato reporters.

CB₁-R-immunoreactive MSN axon collaterals (A) and RGS9 promoter-driven tdTomato expression (A’) overlap (A”) in the dorsolateral striosomes. CB₁-R-immunoreactivity and GAD promoter-driven tdTomato expression also overlaps in dorsolateral striosomes (B-B””) and in the globus pallidus (C-C”). Scale bars are 100 μm. Images were taken with the LSM510.
