“…Somewhat unexpected, however, was the fact that all normal animals scored better than 75% correct. This finding when contrasted with an earlier one, that none of the normal animals were able to solve the dual configuration problem (superimposed triangle and Y runways; Herrmann, 1982), suggests that when there is nothing inherent in the runway configuration to bias the animals (i.e., length or directness), animals have no difficulty discovering and utilizing the invariant relations existing in a complex problem.…”

“…In an unpublished experiment (Herrmann, 1982), it was noted that when the tables were connected by a dual runway configuration in which both a triangular and a Y-shaped configuration were simultaneously present during the test phase, no animal was able to solve the problem at performance levels significantly above chance, even though the animals were given more than 40 daily test trials. Moreover, animals preferred to run on the triangular routes rather than the Y-shaped configuration.…”

The addition of a dual runway configuration did not disrupt the successful performance of normal animals, nor did it improve the deficit of septal rats on the Maier three-table spatial integration task. Both groups of animals displayed a preference for the outside runway configuration during exploration. During testing, however, septal animals retained this preference, whereas normal subjects attempted solution by using the inside runway configuration. This fact, in addition to the apparent lack of a habituation pattern during exploration, suggests that septal animals do not acquire a spatial representation of the test situation. It is suggested that the inability of septal rats in spatial situations is due to an inability to form rather than an inability to use spatial maps.

“…First, a growing amount of evidence shows that rats with frontal lesions are impaired at virtually any delay-type task in which an interval is imposed between some stimulus and the corresponding associated response. Such tasks include delayed alternation (Divac, Wikmark, & Gade, 1975; Larsen & Divac, 1978; van Haaren et al, 1985) and delayed matching and non-matching-to-sample (Brito & Brito, 1990; Brito, Thomas, David, & Gingold, 1982; Kolb, Buhrman, & McDonald, 1989; Herrmann, Poucet, & Ellen, 1985; Poucet, 1990; Poucet & Herrmann, 1990). The lesion evidence is complemented by a few electrophysiological studies that have reported increased neuronal firing of single units in the frontal cortex during the delay period of delay-type tasks (e.g., Batuev, Kursina, & Shutov, 1990; Sakurai & Sugimoto, 1986).…”

Rats with medial prefrontal cortical lesions were tested in a modified water maze navigation task. In Stage 1, the rats were trained to locate a hidden platform from a single start location. They were then subjected to a series of trials during which a second start position was used (Stage 2). In Stage 3, the rats had to navigate to a new goal location from the 2 experienced start positions. Stage 4 required the rats to navigate to the same goal as in Stage 3, starting from 4 distinct positions. Finally, a single probe trial with no platform was conducted. Rats with prefrontal lesions were impaired only during Stage 4. This deficit was specific to the 2 start positions newly introduced during this stage, suggesting a dysfunction of planning processes. This impairment might result from a working memory deficit, precluding the animal from forming an adequate representation of the whole course of movements required to reach the platform.

“…They have also diculties performing spatial maze tasks (Becker et al 1980;Kolb et al 1983;Herrmann et al 1985) Thus, it seems that the prefrontal cortex plays a major role in planning abilities. Our proposal is that the cognitive map could be elaborated in the prefrontal cortex but that the internal representations of transitions could be coded in CA3/CA1.…”

The goal of this paper is to propose a model of the hippocampal system that reconciles the presence of neurons that look like "place cells" with the implication of the hippocampus (Hs) in other cognitive tasks (e.g., complex conditioning acquisition and memory tasks). In the proposed model, "place cells" or "view cells" are learned in the perirhinal and entorhinal cortex. The role of the Hs is not fundamentally dedicated to navigation or map building, the Hs is used to learn, store, and predict transitions between multimodal states. This transition prediction mechanism could be important for novelty detection but, above all, it is crucial to merge planning and sensory-motor functions in a single and coherent system. A neural architecture embedding this model has been successfully tested on an autonomous robot, during navigation and planning in an open environment.
