A what Ch ?
Don't let them fool You, Dr Baumgarten. This is not a watch. It is in fact an alien space ship. Little aliens...but aliens nevertheless.
Definetely not a watch... as we know it, Jim.

C the brain
“I’m very excited about the potential,” said Dr. Atsushi Miyawaki, a researcher on the team, which published its discovery in the journal Nature Neuroscience.
The chemical solution — patented under the name Scale, a phonetic approximation of the Japanese word for “transparent” — could help neuroscientists map the brain’s underlying architecture, though that goal is still a distant one. At the moment, researchers are working to build such a map, called a “connectome,” of mouse brains, which are far less complex than human ones.
Ultimately, this mapping could be conducted on brains of different ages, Dr. Miyawaki said, providing a glimpse into how the organ develops and even how genetic differences might affect that development.

Not so absynth minded ?
Friends , Romans, Countrymen... lend me your ear..
or better read the remarcable story that proves wrong what You thought to be the toxic explanation about the green phantoms of absynth psychosis.
Things that used to be so clearforward and simple, my dear Watson, often tend to be a bit more complex and skewed when viewed in the rear mirror.

A Space Opera
With this bulky machine the OPERA team at CERN tried to hack Einstein and the Special relativity theory proving that some of their 16.000 neurtrono's did indeed tavel faster then c (some nanoseconds). Correct ? hmmm... only if neutrino's would have negative mass.
Pardon me? negative mass ??? Surely You must be joking said Feyneman.
Again such extraordinairy claims demand several extra ordinary proofs.
Fot the moment let's stick to Einstein.

Micromedex
To all practising psychiatrists and physicians large or small who prescibe psychopharmaca: check out this nifty application or better install it right away on your Ipad or Iphone (Ipod will do also). It comes absolutely FRRE ! This should be consulted as much as possible.
Thanks to Steven A. for pointing this little gem out to me out.
Muy obrigado ! Ochaio gozaimas !

As seen on a Brain near You
Brain movies (don't look now !!)
According to Gallant, practical applications of the technology could eventually include a better understanding of what is happening in the minds of those who cannot communicate verbally, such as stroke victims, coma patients and individuals with neurodegenerative diseases.
It may also lay the groundwork for brain-machine interface so that people with cerebral palsy or paralysis can guide computers with their minds.
Nevertheless, researchers emphasize that the brain imaging technology is "decades" away from allowing users to read thoughts and intentions - a theme which is prevalent in numerous dystopian science fiction books. Yet, the achievements of Galant's team are particularly impressive, since the scientists actually decoded brain signals generated by moving pictures.
"Our natural visual experience is like watching a movie," said Shinji Nishimoto, lead author of the study and a post-doctoral researcher in Gallant's lab. "In order for this technology to have wide applicability, we must understand how the brain processes these dynamic visual experiences."
Nishimoto and two other research team members served as subjects for the experiment, as the procedure requires volunteers to remain still inside the MRI scanner for hours at a time.
They watched two separate sets of Hollywood movie trailers, while an fMRI measured blood flow through the visual cortex, the part of the brain that processes visual information. On the computer, the brain was divided into small, three-dimensional cubes known as volumetric pixels, or "voxels."
The brain activity was recorded while subjects viewed the first set of clips which were fed into a computer program that learned, second by second, to associate visual patterns in the movie with the corresponding brain activity.
This is a major leap toward reconstructing internal imagery," explained Professor Jack Gallant, a UC Berkeley neuroscientist and coauthor of the study published online today in the journal Current Biology. "We are opening a window into the movies in our minds."
