1. Had you ever heard that we need sleep after learning to remember the new memories and not forget them? 

​

2. Walker tells us that we also need sleep before learning to actually prepare our brains to take in new information.

​

3. In one study, people who stayed awake all night had a 40-percent deficit in the ability of the brain to make new memories without sleep. 

Is this surprising to you?

 

4. Walker tells us the hippocampus almost like the informational inbox of your brain.  With a full night of sleep, there is lots of healthy learning-related activity, but in those people who were sleep-deprived, we actually couldn't find any significant signal whatsoever. So it's almost as though sleep deprivation had shut down the hippocampus.  All students should be informed of this don't you think?

​

5. Walker explains that there are big, powerful brainwaves that happen during the very deepest stages of sleep that shifti memories from a short-term vulnerable reservoir to a more permanent long-term storage site within the brain.  What do you know about this deep sleep?

​​​

6. We can't get this deep sleep by using sleeping pills, they do not produce naturalistic sleep.  What do you think?

 

7. How does this direct current brain stimulation technology sound to you?. Walker inserts a small amount of voltage into the brain, so small you typically don't feel it, to amplify the size of those deep-sleep brainwaves, but in doing so, he can almost double the amount of memory benefit that you get from sleep. Could there be bad side effects?

 

8. He hopes to translate this same affordable, potentially portable piece of technology into older adults and those with dementia to restore some healthy quality of deep sleep, and in doing so, can we salvage aspects of their learning and memory function.  How does this sound to you?

​

 

9. Walker tell us about sleep loss and our cardiovascular system, because of daylight saving time. Each spring, when we lose one hour of sleep, we see a subsequent 24-percent increase in heart attacks that following day. In the autumn, when we gain an hour of sleep, we see a 21-percent reduction in heart attacks. And you see exactly the same profile for car crashes, road traffic accidents, even suicide rates. Isn't this shocking?

​

10. Our immune system has natural killer cells which identify dangerous, unwanted elements and eliminating them. Walker shows two pictures of immune system cells attacking a cancer cell.  In the second photo, the person has not slept enough so the immune system cells are few, a 70% decrease!  Your comment?

​

11. The link between a lack of sleep and cancer is now so strong that the World Health Organization has classified any form of nighttime shift work as a probable carcinogen, because of a disruption of your sleep-wake rhythms.  What do you think about that?

​

​

12. Walker tells us a simple truth: the shorter your sleep, the shorter your life. Short sleep predicts all-cause mortality. Your comment?
