Recently they even shown single spines in the neurons being erased after sleep. Some new spines are created and some erased. <br>Sleep is both about remembering recent memories and make them stronger (and one of the criterias is that something is repeated over and over has to be important so brain should keep it) and erasing old memories that are not used. <br>The real estate in the brain is extremely precious so the brain needs to erase old, unused memories to make space for new ones.</div><div>This is exactly my area of research and we even developed a device to reinforce memories that are acquired during the day. <br>I have a patent in this area. <br><a href="https://news.northwestern.edu/stories/2017/april/pink-noise-sound-enhance-deep-sleep-memory/">https://news.northwestern.edu/stories/2017/april/pink-noise-sound-enhance-deep-sleep-memory/</a> <br>you can also listen to this podcast:<br><br><a href="https://neurohacker.com/people/giovanni-santostasi">https://neurohacker.com/people/giovanni-santostasi</a> <br><br> <br>Giovanni <br><br> <br><br><br><br><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 26, 2020 at 12:04 PM William Flynn Wallace via extropy-chat <<a href="mailto:extropy-chat@lists.extropy.org">extropy-chat@lists.extropy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:"comic sans ms",sans-serif;font-size:large;color:rgb(0,0,0)">Does anyone know why it is that pro athletes and, just for another example, classically trained musicians need to practice so much?</div><div class="gmail_default" style="font-family:"comic sans ms",sans-serif;font-size:large;color:rgb(0,0,0)"><br></div><div class="gmail_default" style="font-family:"comic sans ms",sans-serif;font-size:large;color:rgb(0,0,0)">My violinist friend said: "If I don't practice today, I know it.
