Effects of the dopamine D-2 receptor agonist, LY 171555, on radial arm maze performance in rats

ED Levin, RE Bowman - Pharmacology Biochemistry and Behavior, 1986 - Elsevier
Rats trained to run through an 8-arm radial maze for food reinforcement were injected with a
broad range of doses of the dopamine D-2 receptor agonist, LY 171555. Deficits were
detected by the choice measures of entries to repeat and arms entered in the first eight
choices. There was a dose-related increase in latency to finish the maze even though there
was no significant increase in the number of choices needed to finish the maze.
