Until now, scientists knew that certain brain waves, such as slow waves, sleep spindles, and oscillations, were associated with memory consolidation. However, their relationship with respiratory rhythms was unknown. In a new study published in the Proceedings of the National Academy of Sciences, scientists show that these brain waves synchronize with breathing during sleep.
The team, led by Professor Cristina Zelano, discovered that waves in the hippocampus, the region of the brain responsible for memory, occur at specific points in the respiratory cycle. This discovery proves that breathing during night sleep is the key to properly consolidating memory.
According to research, sleep-breathing disorders such as apnea can disrupt memory consolidation processes, which has serious consequences on cognitive functions.
