abstract = {The discovery of neuronal systems dedicated to computing
spatial information, composed of functionally distinct cell
types such as place and grid cells, combined with an
extensive body of human-based behavioral and neuroimaging
research has provided us with a detailed understanding of
the brain's navigation circuit. In this review, we discuss
emerging evidence from rodents, non-human primates, and
humans that demonstrates how cognitive aging affects the
navigational computations supported by these systems.
Critically, we show 1) that navigational deficits cannot
solely be explained by general deficits in learning and
memory, 2) that there is no uniform decline across
different navigational computations, and 3) that
navigational deficits might be sensitive markers for
impending pathological decline. Following an introduction to
the mechanisms underlying spatial navigation and how they
relate to general processes of learning and memory, the
review discusses how aging affects the perception and
integration of spatial information, the creation and storage
of memory traces for spatial information, and the use of
spatial information during navigational behavior. The
closing section highlights the clinical potential of
behavioral and neural markers of spatial navigation, with a
particular emphasis on neurodegenerative disorders.},
