      abstract     = {Entorhinal grid cells and hippocampal place cells are key
                      systems for mammalian navigation. By combining information
                      from different sensory modalities, they provide abstract
                      representations of space. Given that both structures are
                      among the earliest to undergo age-related neurodegenerative
                      changes, we asked whether age-related navigational
                      impairments are related to deficient integration of
                      navigational cues. Younger and older adults performed a
                      homing task that required using visual landmarks,
                      self-motion information, or a combination of both. Further,
                      a conflict between cues assessed the influence of each
                      sensory domain. Our findings revealed performance
                      impairments in the older adults, suggestive of a higher
                      noise in the underlying spatial representations. In
                      addition, even though both groups integrated visual and
                      self-motion information to become more accurate and precise,
                      older adults did not place as much influence on visual
                      information as would have been optimal. As these findings
                      were unrelated to potential changes in balance or spatial
                      working memory, this study provides the first evidence that
                      increasing noise and a suboptimal weighting of navigational
                      cues might contribute to the common problems with spatial
                      representations experienced by many older adults. These
                      findings are discussed in the context of the known
                      age-related changes in the entorhinal-hippocampal network.},
