Representative perievent spectrograms showing gamma and theta frequency spectra around CS onset. Perievent spectrograms of local field potential activity from the infralimbic cortex of wild-type and postsynaptic density 95 (PSD-95) mutant mice retrieving a fear memory at recent and remote time points. Theta and gamma power represented by color heat maps: red=high, blue=low. For more info on this topic, please refer to the article by Fitzgerald et al on pages 901–912.
