abstract = {Cellular plasticity at the structural level and sleep at
the behavioural level are both essential for memory
formation. The link between the two is not well understood.
A functional connection between adult neurogenesis and
hippocampus-dependent memory consolidation during NREM sleep
has been hypothesized but not experimentally shown. Here, we
present evidence that during a three-day learning session in
the Morris water maze task a genetic knockout model of adult
neurogenesis (Cyclin D2-/-) showed changes in sleep macro-
and microstructure. Sleep EEG analyses revealed a lower
total sleep time and NREM fraction in Cyclin D2-/- mice as
well as an impairment of sleep specific neuronal
oscillations that are associated with memory consolidation.
Better performance in the memory task was associated with
specific sleep parameters in wild-type, but not in Cyclin
D2-/- mice. In wild-type animals the number of proliferating
cells correlated with the amount of NREM sleep. The lack of
adult neurogenesis led to changes in sleep architecture and
oscillations that represent the dialog between hippocampus
and neocortex during sleep. We suggest that adult
neurogenesis-as a key event of hippocampal plasticity-might
play an important role for sleep-dependent memory
consolidation and modulates learning-induced changes of
sleep macro- and microstructure.},
