Synaptic renormalization during sleep in young mice
- In the primary motor cortex of 2-week old mice, synaptic renormalization occurs normally during sleep compared to adult mice.
Why this matters
- During the day, synaptic functions strengthen to facilitate learning in adults, however, at night synaptic functions renormalize to conserve energy and prevent synaptic saturation.
- It is unknown whether renormalization occurs in children and adolescents as well, because synaptic growth occurs during sleep.
