Further investigation of phenotypes and confounding factors of progressive ratio performance and feeding behavior in the BACHD rat model of Huntington disease
Fig 7
FR5 control test performance during standard and alternative food restriction.
The graphs show comparisons of Group I’s performance on the progressive ratio and FR5 control tests, when rats were maintained on the standard and alternative food restriction protocols. The number of completed ratios (A) and number of lever pushes performed on the reinforced lever (B) were analyzed, as detailed break point analysis could not be performed. The graphs display group mean plus standard error. Repeated two-way ANOVA results are displayed inside each graph, and results from post-hoc analysis are shown for individual data points in case significant genotype differences were detected. (P < 0.05) *, (P < 0.01) ** and (P < 0.001) ***.
