Power of hippocampal gamma rhythms is unchanged in slices from LPA1^−/− mice. A, Example extracellular recordings showing lack of difference in gamma rhythms generated by 100 and 300 nm kainate in hippocampal area CA3 stratum radiatum. Calibration: 0.1 mV, 100 ms. B, Pooled data plots (mean ± SEM; n = 5) for the area power and peak frequency of field potential oscillations as a function of kainate concentration. No effects are seen when slices from control mice (solid lines) and LPA1^−/− mice are compared (dashed lines).
