vHP theta oscillation is not affected in NMDAR-KO mice. A, Power spectral density analysis of LFP signals recorded from vHP in juvenile and adult control and NMDAR-KO mice during desynchronized states expressed as a percentage of the total spectral power. Data are mean ± SEM of n recorded animals. B, Power densities were calculated per band for theta oscillation (3-7 Hz). No statistically significant differences were observed across genotypes. Data are mean ± SEM. Each dot represents 1 individual animal.
