This study demonstrates that fear memory expression is driven by 4-Hz oscillations in prefrontal–amygdala circuits. During fear behavior, prefrontal 4-Hz oscillations lead amygdala and synchronize spiking activity between the two structures. Ultimately, this study identifies 4-Hz oscillations as a physiological signature of fear memories.
