This study looked at how perineuronal nets (PNNs), which are structures surrounding neurons that help regulate brain activity, change throughout the day and night, particularly during sleep. The researchers found that in mice, PNNs decreased during the day and this rhythm was disrupted when the mice were sleep-deprived, resulting in stronger fear memories. In humans, similar changes in PNNs were observed in certain brain areas, suggesting these patterns are important for memory consolidation during sleep.
