“…Thus, as is the case for rats' ability to avoid revisits to maze locations (e.g., Olton & Collison, 1979), odor cues do not appear to be involved in the ability to discriminate locations visited by a foraging partner. Instead, we infer, memory for the choices made earlier in the trial by the other rat is controlling spatial choices.…”

Pairs of rats were tested in a radial-arm maze to determine whether the spatial choices made by one rat affect the subsequent spatial choices of the other rat. In a free-choice procedure, rats showed an increased tendency to choose the location that had most recently been chosen by a foraging partner but a decreased tendency to visit locations that the foraging partner had visited earlier. Forced-choice procedures were used to better control the social stimulus and the interactions between the rats. Under some conditions, locations were chosen later in the choice sequence of a subject rat if another rat had been observed choosing that location. Odor and other physical traces of the other rat's visits were ruled out as explanations for this effect. The results demonstrate the existence of working memory for locations visited by a familiar conspecific.

“…Experiments run in a radial-maze in either the light or the dark, and with either the presence or absence of additional olfactory cues, clearly showed how olfactory cues were only used to guide accurate arm choice when the rats were in the dark (Lavenex and Schenk 1995). Likewise, previous studies have shown how visuospatial cues can outweigh olfactory cues when the two are in conflict (Olton and Collison 1979;Suzuki et al 1980). The present study showed a similar phenomenon but for recognition rather than spatial learning.…”

Two different models (convergent and parallel) potentially describe how recognition memory, the ability to detect the re-occurrence of a stimulus, is organized across different senses. To contrast these two models, rats with or without perirhinal cortex lesions were compared across various conditions that controlled available information from specific sensory modalities. Intact rats not only showed visual, tactile, and olfactory recognition, but also overcame changes in the types of sensory information available between object sampling and subsequent object recognition, e.g., between sampling in the light and recognition in the dark, or vice versa. Perirhinal lesions severely impaired object recognition whenever visual cues were available, but spared olfactory recognition and tactile-based object recognition when tested in the dark. The perirhinal lesions also blocked the ability to recognize an object sampled in the light and then tested for recognition in the dark, or vice versa. The findings reveal parallel recognition systems for different senses reliant on distinct brain areas, e.g., perirhinal cortex for vision, but also show that: (1) recognition memory for multisensory stimuli involves competition between sensory systems and (2) perirhinal cortex lesions produce a bias to rely on vision, despite the presence of intact recognition memory systems serving other senses.

“…Both the opportunity to explore and the access to information may be important determinants of behaviour (COWAN, 1983). In solving a maze task rodents utilize extramaze cues as well as intramaze cues, but many studies point to a major role of extramaze cues and a minor concern of intramaze ones (OLTON & SAMUELSON, 1976;SUZUKI et al, 1980;O'KEEFE, 1983), although it is known that odour trails are able to improve performance in a maze (DAVIS, 1970;MEANS et al, 1971;OLTON & COLLISON, 1979). However, little is reported about individual differences in using extramaze or intramaze cues.…”
