While sleep is known to restore energy, a new study from Cornell University shows it also plays a crucial role in resetting neurons for memory consolidation. Researchers found that during deep sleep, certain parts of the hippocampus, the brain’s memory center, go silent, allowing neurons to reset and prepare for new learning the next day.
The study, published in Science, highlights the hippocampal region CA2 as key to this process, which prevents the brain from overloading as we continue learning throughout life.
This discovery could pave the way for enhancing memory or treating memory-related conditions like Alzheimer’s disease and PTSD by manipulating these neuronal mechanisms.
The research, led by Assistant Professor Azahara Oliva, was supported by several prestigious grants, including from the National Institutes of Health.
