Effects of the D1 receptor antagonist SCH23390 on reconsolidation of cocaine
self-administration in wild-type mice. Wild-type mice were subjected to 3 h
daily self-administration training and showed stable IVSA. Mice then went
through 3 h extinction training daily. Extinction data were from the last day of
training. Once the extinction criterion was met, mice were subjected to a 10-min
retrieval. Reconsolidation was tested 24 h, 48 h or 1 week after the retrieval
(A), or 24 h after no retrieval manipulations (B).
SCH23390 was administered i.p. immediately after the retrieval or during no
retrieval manipulations. N = 6–8 mice for each group. Data
represent mean ± SEM. *P<0.05, **P<0.01,
and ***P<0.001 SCH23390 versus saline treatment.
