Figure 4. Impact of maternal environment on cocaine intravenous SA in C57 and DBA mice.

Figure 4

Graphs show the number of self-infusions obtained in (a) C57 mice in acquisition at 1 mg/kg/infusion (left panel) and dose-response curve (right panel) (b) DBA mice in acquisition at 0.5 mg/kg/infusion (left panel) and dose-response curve (right panel). The symbols in the dose-response graph represent the last two days of stable intake on a dose. Behavior of the reference groups (-bio) is shown with grey lines and symbols. Horizontal lines show the data submitted to statistical analysis. Symbols represent mean±SEM. C57-AKR (white circles) n = 5, C57-C3H (black circles) n = 8, C57-bio (grey circles) n = 8, DBA-AKR (white circles) n = 8, DBA-C3H (black circles) n = 11, DBA-bio (grey circles) n = 10. * p<0.05 compared to DBA-C3H.
