|Mechanics of Sleep
I Don't Know, Steve. This "Sleep" Sounds Risky. How Does It Work? Oh don't worry. It's simple, easy, and convenient. All you need to get is REM sleep .That's short for Rapid Eye Movement sleep.
I know. Right.
At any rate, REM sleep occurs in the Pons and surrounding areas of the midbrain. Now, other bodily functions might make you use accessories available separately, but not us!
Not you? No sir!
Each and every human body is already equipped with the correct areas of the midbrain for sleep! But what if I damage my Pons? You know I never wore a bike helmet as a kid, and those paint buckets smelled so good, and
Well, you might have a bit of a problem then. See, you can't have good, long, restful REM sleep without the Pons being fully functional. Researchers have found that people who have suffered damage or injury to the neurons in the basal forebrain have difficulty falling and staying asleep. You actually may suffer inability to have lengthy REM sleep (REM sleep being what makes us feel rested). Animal studies have found that some neurons within the pons and midbrain are active only in REM sleep while other neurons in this region are entirely inactive only during REM sleep. Together, these neurons control muscle tone and other aspects of REM sleep. In REM sleep, most muscles in the body are turned off. This lack of muscle tone, called atonia, is particularly complete in the muscles of the back, neck, arms, and legs. Less affected are the muscles that move the eyes and the muscles responsible for breathing.
] Er I didn't ask you about muscular activity I just wanted to know about the functionality of my Pons Well, actually you did. You see, the combined effect of the sleep-active and sleep-inactive neurons explains why sleepers do not physically act out the vivid dreams they have during REM sleep. Humans with malfunctioning REM sleep-active and REM sleep-inactive systems thrash around in their sleep, often punching their bedmates or hurting themselves as they act out their dreams.
Oh, sorry. It's quite all right.
Well, I think you've sold me. I'll take some of this sleep stuff. How do I get it? The neurons most critical to NREM sleep control are in the basal forebrain, the region of the brain lying in front of the hypothalamus. Animal studies have shown that this area contains neurons that become most active before and during sleep. Many of these neurons are activated by heat.
So All I would have to do is keep warm? In three easy installments.
What? Your local retailer will hook you up.
Why do you keep trying to answer me like a salesman? I I thought it was funny
No. No, it isn't. Oh.
I'll still try sleeping though. Did you learn anything?
Why yes. I learned so much here that I do wholly believe this site deserves an award. The hell you say.
Oh, yes. This site has enlightened me in ways I could have only dreamed of. Thank you so much. Oh. No problem.
