It has been hypothesized that the rat associative parietal cortex (APC) is involved in the association between visuospatial and locomotion-generated (kinesthetic) information. To study the kinesthetic component, APC-lesioned and control rats were trained in total darkness to reach a submerged platform in the Morris water maze. In the egocentric task, the relative position of the starting point and the platform was constant all over training. Parietal rats have been found impaired in acquisition and to a less extent in retention of this task. In the allocentric task, rats were then trained in the standard version of the navigation task. A mild deficit was observed in acquisition of this task because the APC-lesioned rats displayed longer escape latencies but control-like search patterns. These results suggest that the APC is involved in the coding of kinesthetic information that plays an important role in place navigation.
