“…Running was tested in two similar 3S-cm-diam unidirectional wheels constructed of Plexiglas sides with grid floors. For further details, see Lyons and Freedman (1982). Each apparatus was located in an insulated wooden box that was open on the front for easy viewing and could be observed from an adjacent room via a window.…”

Reward-dependent suppression or facilitation of consummatory behaviour by raclopride

Rats were presented for 1 h with 0.7%, 7% or 34% sucrose solutions, either separately with water as an alternative (two-bottle test), or with all three concentrations concurrently available (three-bottle test). In trained animals, 7% sucrose produced the highest intakes in the two-bottle test, but 34% sucrose was preferred in the three-bottle test. In both tests the dopamine D-2 antagonist raclopride (100-400 micrograms/kg) reduced intake of 0.7% sucrose solution, but increased intake of 34% sucrose; both effects were apparent during the first 5 min of testing. In the two-bottle test, intake of the intermediate 7% concentration showed both effects: an immediate decrease and a later increase. In the three-bottle test, sucrose-naive animals showed a gradual onset of preference for 34% sucrose, and enhancements of intake by raclopride were not at first immediate; immediate enhancements required three sessions of exposure. Raclopride did not alter the consumption of a 0.001% solution of quinine. We consider the implications of these results for theories of neuroleptic drug action.
