Figure 2 |. Novelty reorganizes vHPC activity patterns.
a, Left, normalized LFP examples. Right, vHPC theta power during novelty (novel: 14, familiar: 16 mice; Mann-Whitney test, P = 0.001). Inset, average theta power of each mouse. b, Left, the ratio of vHPC units phase-locked to local theta oscillations (Chi-square test, P = 0.03; novel: 29, familiar: 26 cells). Right, vHPC unit firing rate in the novel group (Mann-Whitney test, P = 0.04). Cumulative distribution shows all single unit values. c, Left, examples showing normalized theta filtered LFP and vHPC single-unit spikes (ticks). Right, preferred theta phases at which vHPC units fired (Kolmogorov-Smirnov test, P = 0.01). * P < 0.05. ** P < 0.005. Data are represented as mean ± SEM.
