abstract = {Flexible spatial navigation, e.g. the ability to take novel
shortcuts, is contingent upon accurate mental
representations of environments-cognitive maps. These
cognitive maps critically depend on hippocampal place cells.
In rodents, place cells replay recently travelled routes,
especially during periods of behavioural inactivity
(sleep/wakeful rest). This neural replay is hypothesised to
promote not only the consolidation of specific experiences,
but also their wider integration, e.g. into accurate
cognitive maps. In humans, rest promotes the consolidation
of specific experiences, but the effect of rest on the wider
integration of memories remained unknown. In the present
study, we examined the hypothesis that cognitive map
formation is supported by rest-related integration of new
spatial memories. We predicted that if wakeful rest supports
cognitive map formation, then rest should enhance knowledge
of overarching spatial relations that were never experienced
directly during recent navigation. Forty young participants
learned a route through a virtual environment before either
resting wakefully or engaging in an unrelated perceptual
task for 10 min. Participants in the wakeful rest condition
performed more accurately in a delayed cognitive map test,
requiring the pointing to landmarks from a range of
locations. Importantly, the benefit of rest could not be
explained by active rehearsal, but can be attributed to the
promotion of consolidation-related activity. These findings
(i) resonate with the demonstration of hippocampal replay in
rodents, and (ii) provide the first evidence that wakeful
rest can improve the integration of new spatial memories in
humans, a function that has, hitherto, been associated with
sleep.},
