To Sleep, Perchance to Clean

Posted on by Kari Kenefick

While you and I are getting some shut eye each night, things are happening in our brains. Good things. Therapeutic things.

Think of it as brainwashing of a sort. There is a multiplicity of brain activities going on during sleep, and a November 1 paper in Science shows for the first time when and where in the brain these activities occur, and how they are connected.

CSF washes through the brain.

Here’s a bit of backstory.

To assess both the progression and pathogenesis of Alzheimer’s disease (AD), as well as the efficacy of AD drugs in clinical trials, there has been interest in the concentrations of amyloid-beta (Aβ) and tau protein in cerebral spinal fluid (CSF).

To Meditate Perchance to Dream

First the disclosure: this blog is of course about Me.

But it’s also about You. And yours. Because as you know, we’ve become a culture that does not sleep.

Why don’t we sleep? I like to think that it is an evolutionary adaptation; not sleeping, after all, allows us more time for Facebook.

Or Etsy for you makers. Or Amazon for you shoppers. And let’s not forget our middle, high school and college students. Do they even have classrooms anymore, or are lectures all online (on screens)?

Honestly, the evolutionary adaptation idea comes from how we live and work today. And no, this is not another rant/lecture on the color of light emitted by whatever non-cathode ray tubes are in our phones or tablet-like devices.

It’s just that just working in our very busy online/wired world, jumping from web page to project management software, to big-screens in meetings has us adapted to being  on: capital “O” capital “N”.

This multi-multitasking has grown (for me) a new type of neurons that are not happy unless they are gleaning new information from a screen, all the time. And these neurons don’t stop working when the screen is gone; no, they continue seeking and trying to process. For me, if there’s no screen to look at, the neurons ping-pong around behind my eyeballs, looking and searching, as if to say, “Input missing! Input missing!”

The result can be hours in bed sans sleep; it seems the racket these neurons make keeps all the other neurons up. Continue reading “To Meditate Perchance to Dream”

Sleep Well Today to Learn Well Tomorrow

Sleep, defined as a state of reversible disconnect from the environment (1), is an integral part of life. In this fast-paced life, you might think of sleep as a waste of time and unnecessary, impinging on productivity. But, nothing can be farther than the truth. Sleep researchers around the world are trying to understand what is the most important physiological function of sleep. It is too simplistic to say that sleep rests the brain, and it is not entirely true since neuronal activity in many parts of the brain do not slow down appreciably during sleep. So, what does sleep do? Continue reading “Sleep Well Today to Learn Well Tomorrow”
