I think it's really interesting how sleep can actually be more beneficial towards your goal than actually practicing for it, like the example with the test and piano performance. This is because during sleep, you hippocampus sends memory to the neurons in your brain, further strengthening your short term memories so they can gradually become long term memories. It is as if you only have to study a little bit, and than reinforce it during sleep.

I thought that this video was very cool however, I didn't think it told us very much about all the different things our brain does for us during sleep. I thought it talked too much about memories and not enough about the rest of the things your body does during your sleep. I liked the examples that they video showed because I have been in that exact situation before, and it is not fun. Over all I learned a lot from this video and enjoyed watching it.

Derek said...

I agree with Siji and Jenna. I think that it is very interesting how sleep can be more useful then studying or practicing. I think that it is very cool how the hippocampus can sends memory to the brain, it is also very cool how how sleeping can help develop your short term memory. I think that the overall message of this video is that it is more efficient to study a little but then sleep on it and your brain will start to but the information in its long term memory.

I believe that this video was really interesting. In a way, sleeping is a shortcut! Instead of practicing and practicing over and over again, you could practice it once (whatever it is) and go to bed for a few hours and you'll remember. I really enjoyed the examples that the video showed. Especially the part about H.M. So technically, they discovered that the hippocampus was connected to memory, on accident! Science is full of so many different ideas. I think that it was extraordinary to watch the waves traveling through the brain from the hippocampus to the cortex. This video was awesome and it had a little life hack incorporated in it. So that's always a plus. I would definitely recommend this video to fellow scientists. This was an epic 5 minutes of watching the TedED talk

Sorry, I forgot the period at the end

And Again.

I think that the video was interesting, but I think that it should be called, "One Benefit of a Good Night's Sleep." I agree with Jenna that I would have liked to have seen some other benefits of a good night's sleep. I thought that how much that all of what the hippocampus does is cool. Now I understand more of how short term memories can become long term memories.

Lily said...

I thought that this video was very interesting and informative. I liked learning that sleep is good for studying, and helps you remember things. I now understand how I can help short term memories become long term ones. It is because when you are sleeping, the hippocampus sends memory to the neurons that are in your brain. I learned that a better way of studying for a test is to do a little bit, and then go to sleep. I already knew that doing a lot of studying or practicing in one night didn't do a lot for you, but I never knew why.

I think this video was very interesting. It is cool how sleeping for several hours can be more beneficial than studying for several more hours. Sleeping is a way of regulating your body, and it is great for your body, especially your brain. While you are sleeping, your brain is kind of reconstructing, a phase that is crucial for your memory. It was also disbelieving that a psychologist proved that we forget about 40% of new material in the first 20 minutes (phenomenon known as Forgetting Curve)! However, this can be stopped with memory consolidation, using the hippocampus. It is cool how the hippocampus is responsible for the memories. This video was very interesting, about how sleeping can retain memory better than studying last minute.

Natalie said...

I liked this video/lesson, and now I know this: if I have to study last-minute for a test, I should learn then go to sleep. I found it interesting how the hippocampus only helps remember certain activities, ones that aren't repetitive. I liked how they based this video off a test and a piano recital, because it shows that even if you don't have much time for 2 activities the next day, if you sleep, (which is awesome because you get to sleep), it will help you learn the material better.

Rohan said...

This video was really interesting. I ussually do the exact opposite of what it is telling me. I find it really suprising that we lose 40% of what we learn in 20 minutes. However I am confused when it said it is best to go to sleep 3 hours after studying. Isn't it possible that people would forget things during that 3 hour period.

Julianna R said...

This article was very informative. I have heard something similar to this before. It is VERY true, sleep calms you down and refreshes your brain. VERY helpful! Some place has to store your memory and it's the hippocampus. I wouldn't argue with the fact that your hippocampus is very important because it stores all your memory. The hippocampus is very valuable, and you should try your best not to lose it. Sleep supports the hippocampus and many more. Overall, sleep is very important and everyone should get enough of it.

Olivia said...

First, I would like to say that I have always thought of sleep as lost time. The average female lives to be 81 and the average male lives to be 76. That turns out to be about 25 - 27 years spent sleeping. This video has definitely changed my views on sleep. This video explained that you do not lose time to make memories, but you keep them active in your brain. However, I have noticed that when you do have a big test or piano recital coming up and you try to go to sleep, all one can think about is the anxiety they have towards these things. I wish that this video expanded a little bit more on your brain and why it doesn't let you sleep. But overall, this video kept me very interested and it helped me understand why sleep is crucial.

This was a very cool thing to be put on the blog and thanks Jaime for putting it on there but it was way too repetitive for me. There was only one thing mentioned in the video and stated in different ways and that is the short/long-term memory. I do think that the emotional parts were true because when I have a normal memory of looking in the mirror, I tend to forget it faster than I do getting a B on a test. (Yes, I get very mad when I get B's) The cool things that the hippocampus does is cool and the HM person who had it removed proved Brenda's point. I loved the video but the guy talking should have said a few more things other than the memory stuff. This was cool and I hope we have more brainy links on the blog soon!

Ayden said...

This was a rather helpful article on sleep. Now that I know this, I should definitely get more sleep. I can't believe that we lose about 40% of what we learn in just 20 minutes! It's good that there is a way to prevent less memory to be lost. It was interesting how your brain works while you sleep, especially in the slow wave sleep, when your memory goes from the hippocampus to the cortex, where it is stored as long term memory. The hippocampus is also interesting in how it works on declarative memory, and how when you remove it, you can only consolidate your procedural memory.

Ella said...

It is very cool how sleep is better that studying and cramming everything in the night before. I should try doing that! However, I find it very interesting how when we sleep, our brain is regenerating. It is very scary how people forget 40 percent of what they're learning in 20 minutes. This video was really good and informative. I never knew how great sleeping really is!

Rhea M. said...

I thought that the study on the man who's hippocampus was take out learned more things faster but other things were slower and not able to be learned. I also learned that the hippocampus is beneficial to you long sand short term memory and without it you can't learn many things. Im also going to try to go to sleep 3 hours after studying and 1 hour after music practice

Jaime said...

I think this video was very informative. It was cool how declarative memory is half of your brain and procedural memory is the other half, so if you are trying to study and remember your dance movements, in one night. You probably won't remember forty percent of it, because of the forgetful curve. Your hippocampus is what helps the rotation of memories. If you go to sleep three hours after trying to remember your declarative memory, and one hour after trying to remember you procedural memory, you will wake up better than ever, and with a refreshed brain.

Allie said...

I agree with everyone here. It is amazing how sleep is more useful than studying! Next time my parents make me study late, I will be like, "Watch this video. Yes, sleep is better." If you sleep, boom! You know more! I really agree with Jason where he said "sleeping is a shortcut" because yes, it is. Also, I never thought sleep as lost time. This just proved that my assumption was correct. All in all, I really enjoyed this video, and learned a lot from it. I guess I should try harder to sleep earlier even if I want to play a game or read...

Oliver said...

I thought that this video was very cool because it taught me that sleeping is just as if not more than important as studying. I did not know that while we are sleeping our brain is restructuring and storing our memories. It also taught me that during sleep the short term memories go into the hippocampus and come out as long term memories. I thought this was a good video on the brain and sleep.

Celene A. said...

This was really cool thing and thanks Jaime for suggesting it. :) Although, it was extremely repetitive. It was interesting to learn about the long vs. short term memory but we already learned about this last year.

Lennox said...

I think that this video was interesting. I liked how the removal of H.M.'s hippocampus led to him not able to have long term memory. I liked how sleep can help. I also liked how you forget new material in the first twenty minutes.

Eli said...

This is really interesting how cramming and staying up all night is not the best way to study for the test. I never thought that cramming was the best way to study, but I never imagined sleeping would help. In addition to it helping your memory, your bound to do better if you are well rested than if you have barely slept. I would be interested to do a study on this, and it a very cool subject.

Xavier C said...

I actually disagree with this method. I have tried it before many times and I did not do so well on a test. I did think it was cool how the hippocampus was one of the main parts of processing things you have learned into your long term memory. I also thought that it was cool that you forget up to 40% of what you have just learned. That is probably why people think they should stay up late and keep practicing where sleep actually is the key. (But in my opinion work is the key.)

Sydney said...

I thought that this video was really helpful. For those of us who have trouble remembering things, this is the solution! I still kind of want to know some other things that the brain does when we're asleep. Also, why is it that we should go to bed three hours after studying math and one hour after practicing piano?

Mina said...

I think it's really interesting that sleep actually has a really big impact on your memory, and brain in general. I mean, I've heard it passing in conversations before, but I never considered the fact that it actually affects you this much! I'm extremely excited about this topic, and am going to do some research on it!
