Gamma frequency oscillation in the hippocampus of the rat: intracellular analysis in vivo
Abstract
Gamma frequency field oscillations reflect synchronized synaptic potentials in neuronal populations within the ≈ 10–40 ms range. The generation of gamma activity in the hippocampus was investigated by intracellular recording from principal cells and basket cells in urethane anaesthetized rats. The recorded neurones were verified by intracellular injection of biocytin. Gamma frequency field oscillations were nested within the slower theta waves. The phase and amplitude of intracellular gamma were voltage dependent with an almost complete phase reversal at Cl– equilibrium potential in pyramidal cells. Basket cells fired at gamma frequency and were phase‐locked to the same phase of the gamma oscillation as pyramidal cells. Current‐induced depolarization coupled with synaptically induced inhibition resulted in gamma frequency discharge (30–80 Hz) of pyramidal cells without accommodation. These observations suggest that at least part of the gamma frequency field oscillation reflects rhythmic hyperpolarization of principal cells, brought about by the rhythmically discharging basket neurones. Resonant properties of pyramidal cells might facilitate network synchrony in the gamma frequency range.

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.
