Popis: Neither septal nor fornix lesioned rats were able to successfully perform the Maier 3 table reasoning task. Detailed analysis of the performance patterns of both groups reveal a common feature of primary dependence on directional responses at the choice point. This response strategy, as opposed to the spatial strategy attributed to normal animals, does differentiate between the two lesion groups. Septal lesioned subject show a dependence on a preferred or dominant direction of turning at the choice point both within and over trials. Fornical lesioned animal demonstrate the same pattern but only over trials. In addition, fornical lesioned rats tend to continue responding even though they had successfully reached the goal table. It is argued that fornical lesioned rats may not be able to use spatial information while septal rats who evidence repetitive errors, made by alternating between environmental locations, may attempt to acquire and unsuccessfully use spatial information.
