Each section lists the results of t tests comparing performance of animals with DSL, HPC, or DSM lesions to the performance of corresponding sham groups. The tests were planned a priori and run after the results of the two-way mixed analyses indicated highly significant main effects and interactions; the degrees of freedom were computed based on Welch–Satterthwaite equation.
