Cellular and Network Mechanisms Underlying Spontaneous Sharp Wave–Ripple Complexes in Mouse Hippocampal Slices
Open accessAbstract
The mammalian hippocampus displays a peculiar pattern of fast (≈200 Hz) network oscillations superimposed on slower sharp waves. Such sharp wave–ripple complexes (SPW–R) have been implicated in memory consolidation. We have recently described a novel and unique method for studying SPW–R in naive slices of murine hippocampus. Here, we used this model to analyse network and cellular mechanisms of this type of network activity. SPW–R are usually generated within area CA3 but can also originate within the isolated CA1 region. Cellular synchronisation during SPW–R requires both excitatory and inhibitory synaptic transmission as well as electrical coupling, the latter being particularly important for the high‐frequency component. Extracellular and intracellular recordings revealed a surprisingly strong inhibition of most CA1 pyramidal cells during SPW–R. A minority of active cells, however, increases action potential frequency and fires in strict synchrony with the field ripples. This strong separation between members and non‐members of the network may serve to ensure a high signal‐to‐noise ratio in information processing during sharp wave–ripple complexes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
