FIG. 6.

Total trials to reach criterion in digging attentional set-shifting task (dAST, groups collapsed regardless of surgery or treatment) on post-injury day (PID) 25–27. Rats exposed to odor first as the relevant dimension (as opposed to medium) in dAST required significantly more trials to complete the compound dimensional (CD) stage of dAST (A), but total trials to criterion throughout the dAST day were unaffected between the two extradimensional (ED) shifts (B) and were not significantly different. n = 30, mean (± standard error of the mean), *p < 0.01 odor-to-medium versus medium-to-odor.
