The bar charts in the top two rows show the results of an object location test (OLT). Cartoon A shows the various phases involved in OLT, whereas the bar charts in B-D show the performance of animals belonging to naïve, sedentary GWI rats (GWI-SED) or GWI rats that performed RE (GWI-RE). The bar chart E compares the discrimination index across the three groups. The bar charts F-H compare the total object exploration times (TOETs; F), the distance traveled (G), and velocity of movement (H) in trial-3 (T3) between the three groups. The bar charts in rows 3–4 show the results of a pattern separation test (PST). The cartoon in I shows the various phases involved in PST, whereas the bar charts in J-L show the performance of animals belonging to different groups. Bar chart M compares the discrimination index across groups. The bar charts N-P compare TOETs (N), the distance moved (O), and the velocity of movement (P) in T4. The bar chart Q shows the results of a novelty suppressed feeding test. *, p < 0.05, **, p < 0.01, ***, p < 0.001.
