Retroactive and proactive errors at each of the four delays in postoperative testing for control and BF-lesioned rats, across all 12 d of postoperative testing. Retroactive errors (entries into maze arms visited before the delay) increase as the delay between sample and choice increases, but BF-lesioned rats perform comparably to control rats at each of the four delays. Proactive errors (re-entries into arms visited after the delay) do not vary with delay and also do not differ between control and BF-lesioned rats.
