Ken Wilber can stop his brain waves on demand. This
(WMV) is the famous EEG machine recording where Ken Wilber
enters various meditative states, one of which is a type of "thoughtless," "image-less," or "formless" state, whose correlate is that his brainwaves come to an almost complete stop, as clearly recorded on this portable electroencephalograph (EEG) machine. Seeing somebody's brainwaves flatline in about 4 seconds is a sight not easily forgotten! Also on YouTube

Treasure Hunt Puzzle
I've been nutting my way through some of these puzzles with some difficulty but with a great deal of fun. Thought I would share...

Most everybody's asleep in Grover's Corners. There are a few lights on: Shorty Hawkins, down at the depot, has just watched the Albany train go by. And at the livery stable somebody's setting up late and talking. -- Yes, it's clearing up. There are the stars - doing their old, old crisscross journeys in the sky. Scholars haven't settled the matter yet, but they seem to think there are no living beings up there. Just chalk... or fire. Only this one is straining away, straining away all the time to make something of itself. The strain's so bad
that every sixteen hours everybody lies down and gets a rest.
Hm... Eleven o'clock in Grover's Corners. -- You get a good rest,
too. Good night.

Japanese professor Kenji Sugimoto has a long-standing fascination with the brain of Albert Einstein. In the early nineties he travelled to the United States in search of it. This bizarre 1994 documentary
(YouTube, multiple parts
) by Kevin Hull (UK) chronicles his quest. Fake or real? [more inside]

So, how many subjects are there in a split brain
? I know that at least one more mefi user is interested
. To get some background information, play this little game
from nobelprize.org. Personally, I think they
(even though the layout
is strange - for an edu site) have it right: [more inside]

Italian & German researchers have created a "neuro-chip" for linking computers with mammalian neurons (A NewScientist
). They added neuron gluing proteins to the chip to attract the sodium pores, and genetically modified the neurons to add more sodium pores.
In the short term, the work is expected to aid the pharmaceutical industry in testing the effects of drugs on neurons, assist basic research into the workings of the brain, and perhaps help treat neurological disorders. In the long term, numerous sci-fi technologies are slightly closers, such as computers with living components, useful brain implants, and Beowulf clusters of humans.

New hope for blind hamsters.
According to the Guardian, scientists at MIT have repaired brain damage and restored eyesight to rodents using nanotechnology. In the study, minute particles were injected into damaged parts of the brain, and subsequently arranged themselves into a "scaffold" gel throughout the damaged area. The scaffold allowed severed nerves to regrow and form new connections. 75% of test animals' injuries were improved with the new technique. (The article did not note if the test subjects offered any resistance to the therapeutic measures.)

themselves to be provided with clean blades so that they can cut themselves more safely.

The strange story of Henry M
. Henry was able to hold information in storage for very short periods of time. Most people can retain about seven pieces of information (a telephone number, for example) in memory for about thirty seconds, and Henry scored normally on these kinds of tasks. Thus, his working memory (or scratch-pad memory) seemed unaffected by the loss of his hippocampus. The main problem for Henry was converting short-term memories into permanent storage, a process called consolidation. Henry's case
is one of the most studied brain-damage cases
[PDF] ever. A fascinating story about one man's struggle with brain surgery.

Don't Even Think About Lying
fMRI is poised to transform the security industry, the judicial system, and our fundamental notions of privacy. I'm in a lab at Columbia University, where scientists are using the technology to analyze the cognitive differences between truth and lies. By mapping the neural circuits behind deception, researchers are turning fMRI into a new kind of lie detector that's more probing and accurate than the polygraph, the standard lie-detection tool employed by law enforcement and intelligence agencies for nearly a century.
