Sleep—a brain-state serving systems memory consolidation

S Brodt, M Inostroza, N Niethard, J Born - Neuron, 2023 - cell.com
Although long-term memory consolidation is supported by sleep, it is unclear how it differs
from that during wakefulness. Our review, focusing on recent advances in the field, identifies …
