D2 DA receptor densities (fmol/mg protein) in the posterior striatum after injection into the midbrain of pTHpkcΔ, pTHpkcΔGG, or PBS

Condition	Hemisphere	Ventromedial	Posterior striatal region		Dorsolateral
Condition	Hemisphere	Ventromedial	Ventrolateral	Dorsomedial	Dorsolateral
pTHpkcΔ	Injected	321 ± 25*	598 ± 73*	299 ± 42	422 ± 61
n = 4	Noninjected	284 ± 30	549 ± 73	280 ± 42	410 ± 57
pTHpkcΔGG	Injected	245 ± 25	499 ± 73	211 ± 42	324 ± 61
n = 4	Noninjected	242 ± 30	521 ± 73	222 ± 42	344 ± 57
PBS	Injected	246 ± 28	550 ± 84	287 ± 48	424 ± 70
n = 4	Noninjected	226 ± 34	563 ± 84	304 ± 48	433 ± 66

Two weeks after gene transfer, D2 DA receptor levels were determined in each of four quadrants in the anterior, medial, and posterior striatum. The D2 DA receptor levels (mean ± SEM) in the posterior striatum are shown here. D2 DA receptor density in the injected hemisphere was significantly greater than in the control hemisphere of rats in the pTHpkcΔ group (p < 0.05), but not in the control groups, as determined by ANOVA.
