Extent and location of the cMEC lesions. a, Area measurements. Gray, Smallest lesion; black, largest lesion. b, Unfolding the cMEC revealed that damage was restricted to the cMEC. Seven individual lesions are represented. The dashed black line represents the dorsal border of the cMEC and the thick continuous black line represents the ventral border of the cMEC, according the rat brain atlas of Watson and Paxinos. The unfolded map is restricted to the mediolateral levels ± 3.4–5 (yellow lines) and the anteroposterior levels −7.5 to −10. D–V, Dorsoventral axis; L–M–L, mediolateral axis.

ROC curves and recollection and familiarity indices for odor recognition memory. a, Standard ROC functions for item recognition. Both preoperative groups used recollection and familiarity to solve the task, as reflected by asymmetrical and curvilinear ROC curves, and recollection and familiarity indices did not significantly differ between preoperative groups (insert). b, Rats with MEC damage were impaired in recollection, as shown by a decrease of the y-intercept and a drop of the recollection index (insert), whereas familiarity remained unaffected and performance of controls was unchanged following sham surgery. Error bars represent SEM; Controls, Sham-operated rats; MEC, rats with MEC lesions.
