Subjects were trained in a simple navigation task. During data acquisition, the subjects location within the environment was unexpectedly perturbed. BOLD signal changes related to the perturbation of the subjects location in the environment were detected within the parietal cortex bilaterally. The activity was stronger on the left for males and stronger on the right for females. By controlling for all other aspects of the task, we believe we have demonstrated that this functional activity is related to the maintenance of a spatial topological map of the environment.
