text: Sharp wave-ripple (SWR) oscillations play a key role in memory consolidation
during non-rapid eye movement sleep, immobility, and consummatory behavior. However,
whether temporally modulated synaptic excitation or inhibition underlies the ripples
is controversial. To address this question, we performed simultaneous recordings
of excitatory and inhibitory postsynaptic currents (EPSCs and IPSCs) and local
field potentials (LFPs) in the CA1 region of awake mice in vivo. During SWRs,
inhibition dominated over excitation, with a peak conductance ratio of 4.1 ± 0.5.
Furthermore, the amplitude of SWR-associated IPSCs was positively correlated with
SWR magnitude, whereas that of EPSCs was not. Finally, phase analysis indicated
that IPSCs were phase-locked to individual ripple cycles, whereas EPSCs were uniformly
distributed in phase space. Optogenetic inhibition indicated that PV+ interneurons
provided a major contribution to SWR-associated IPSCs. Thus, phasic inhibition,
but not excitation, shapes SWR oscillations in the hippocampal CA1 region in vivo.
