  bibo_abstract:
  - The hippocampus has a major role in encoding and consolidating long-term memories,
    and undergoes plastic changes during sleep1. These changes require precise homeostatic
    control by subcortical neuromodulatory structures2. The underlying mechanisms
    of this phenomenon, however, remain unknown. Here, using multi-structure recordings
    in macaque monkeys, we show that the brainstem transiently modulates hippocampal
    network events through phasic pontine waves known as pontogeniculooccipital waves
    (PGO waves). Two physiologically distinct types of PGO wave appear to occur sequentially,
    selectively influencing high-frequency ripples and low-frequency theta events,
    respectively. The two types of PGO wave are associated with opposite hippocampal
    spike-field coupling, prompting periods of high neural synchrony of neural populations
    during periods of ripple and theta instances. The coupling between PGO waves and
    ripples, classically associated with distinct sleep stages, supports the notion
    that a global coordination mechanism of hippocampal sleep dynamics by cholinergic
    pontine transients may promote systems and synaptic memory consolidation as well
    as synaptic homeostasis.@eng
