Spatial patterns and memory for locations
Rats obtained food from the tops of vertical poles in a 5 X 5 matrix of locations. On each trial, the baited locations formed one of the two possible exemplars of a checkerboard spatial pattern. During training, locations that had been visited earlier in the trial were indicated by a visual cue. Following training, performance with and without the visual cues was compared. Spatial choices were controlled by the checkerboard spatial pattern. The visual cues enhanced the ability of rats to avoid revisits of locations. However, the visual cues did not enhance control by the spatial pattern, as would be expected if the same spatial memories were involved in avoidance of revisits and coding the location of baited locations.
