[Oe List ...] Sleep

[Susan Fertig]

I remember going sleepless, and EI/ICA told us it was nothing. Now there are reports out that beg to differ.

>From the National Geographic:


The hippocampus, located within the inner region of the temporal lobe of the brain, close to the base of one's skull, plays a significant role in this undertaking. Spencer calls the hippocampus, "a short-term storage site" for the things we learn. She says that's where information gets piled up throughout one's day like papers on a work desk. "When you sleep, those 'papers' are filed away into a long-term filing cabinet to be retrieved as needed." This long-term storage site is the cerebral cortex-the large, outer layer at the top of one's cerebrum.

Spencer says this transferring process can take up much of the night, and that if we don't get enough sleep, we may wake the next morning with some lessons or memories not yet transferred-causing them to become fuzzy when trying to recall them later.

Getting sufficient sleep also helps the brain experience the benefits of each sleep stage<https://www.nationalgeographic.com/magazine/article/science-of-sleep>-a critical element of embedding memories, per PNAS research published last year<https://www.pnas.org/doi/10.1073/pnas.2123432119>. "Sleep helps us better cement what we have learned into long-term memory," explains David Creswell, a professor of psychology at Carnegie Mellon University.

I found this very interesting. I probably don't get enough sleep-I wake in the middle of the night and can't get back to sleep.
