In vivo recording in CA1 demonstrates alterations in hippocampal rhythmic oscillations and firing rates in Nf1 +/− mice. a The local field potentials (LFPs) recordings in CA1(WT mice). First trace- unfiltered LFPs, second trace- alpha oscillations (filtered 7–12 Hz). b Histograms show the averaged power spectral density of the neuronal rhythmic oscillations (alpha). Data are expressed as mean ± SEM (WT, n = 5; Nf1 +/− , n = 5). Two-way analysis of variance with repeated measures and post hoc Bonferroni tests was used to evaluate differences in local field potential power spectrum density in day and night recordings in Nf1 +/− and WT groups. ***p < 0.001.
