Rapid Changes in the Light/Dark Cycle Disrupt Memory of Conditioned Fear in Mice

BACKGROUND Circadian rhythms govern many aspects of physiology and behavior including cognitive processes. Components of neural circuits involved in learning and memory, e.g., the amygdala and the hippocampus, exhibit circadian rhythms in gene expression and signaling pathways. The functional significance of these rhythms is still not understood. In the… CONTINUE READING
