Losing sleep undoes the rejuvenating effects new learning has on the brain

Losing sleep undoes the rejuvenating effects new learning has on the brain

As the pace of life quickens and it becomes harder to balance home and work, many people meet their obligations by getting less sleep.

But sleep deprivation impairs spatial learning � including remembering how to get to a new destination. And now scientists are beginning to understand how that happens: Learning spatial tasks increases the production of new cells in an area of the brain involved with spatial memory called the hippocampus. Sleep plays a part in helping those new brain cells survive.

A team of researchers from the University of California and Stanford University found that sleep-restricted rats had a harder time remembering a path through a maze compared to their rested counterparts. And unlike the rats that got enough sleep, the sleep-restricted rats showed reduced survival rate of new hippocampus cells.

Why magazine websites still don't get it = Bussiness 2.0 My golden rule

Monday, January 09, 2006
Here's Business 2.0, which is supposed to be a "hi-tech magazine" - one would think they would know how to use the web.

Want to read 49 Golden Rules by 49 business leaders? You get 4 on the link page and 45 others on a pop-up which have one each.

The magazine wants you to click 49 times to read one paragraph each !!! Don't cry, it gets worse.

Where is the golden rule you might ask - it is Photoshopped on the photo !!!

You can't even select it as text !!!

Want to link to a specific one? You are out of luck - it's hidden in some javascript - the people at AOL-Time-Warner think that's too much; they want you to go to the link page and use the pop up every time.

A company with the market-cap of $80+ Billion should be able to do much better than that.

BUSINESS 2.0: My golden rule - Nov. 28, 2005: "49 leaders, from Buffett to Spitzer, share their secrets to success."
