@entity35 with perirhinal cortex (PRC), hippocampal, or sham lesions were trained on a successive discrimination go/no-go task to examine recognition memory for an array of visual objects with varying interference among the objects in the array. @entity35 were trained to recognize a target array consisting of four particular objects that could be presented in any one of four possible configurations to cover baited food wells. If the four target objects were presented, the @entity35 should displace each object to receive food. However, if a novel object replaced any one or more of the target objects, then the @entity35 should withhold its response. The number of novel objects presented on nonrewarded trials varied from one to four. The fewer the number of novel objects in the array, the more interference the array shared with the target array, therefore increasing task difficulty. An increased number of novel objects should result in less interference with the target array and decreased task difficulty. Although accuracy was slightly lower in @entity35 with @entity75 compared with controls, the learning of the groups was not statistically different. In contrast, @entity35 with PRC lesions were significantly impaired in learning compared with both control and hippocampal-lesioned @entity35 . The results suggest that recognition @entity227 is affected by stimulus interference in rodents with @entity16 .
