Vegetated State conversations: To find out whether a simple conversation was possible, the researchers selected one of the four - a 29-year-old man who had been in a car crash. They asked him to imagine playing tennis if he wanted to answer yes to questions such as: Do you have any sisters? Is your father's name Thomas? Is your father's name Alexander? And if the answer to a question was no, he had to imagine moving round his home.

Neurosecurity: security and privacy for neural devices.
"An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define 'neurosecurity'—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices."

We've discussed trepanation
, the boring of holes in the head as practiced in antiquity and by a fringe do it yourself-ers, before. There now seems to be research indicating that the procedure may have medical merit
, and even help stave off age related cognitive decline. This curious research brought to you by the Beckly Foundation
which "promotes the investigation of consciousness and its modulation
from a multidisciplinary perspective" and has a sweet logo.

Sgt. Wells's New Skull. In the epidemic of brain injuries coming out of the war, Army neurosurgeons had never seen someone survive such a devastating wound. But Brian Wells jokes that he just left part of his head in Iraq. Someday, he says, he'll have to go back and get it.

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.)

Nootropics ("smart" drugs)
- all wish to be smarter, correct ? And - while exercise, nutrition, learning, travel, and social interaction (the last 3 via release of neurotrophins
) effectively do this, Nootropic drugs have been researched since the 1950's and have been shown to cause at least short term cognitive function enhancement. Piracetam, the first of this drugs, shows promise
in the treatment of Alzheimer's and Attention deficit Disorder. Alas, as with poor little Algernon
, the effect seems temporary
. Nootropics can be a little difficult to acquire
in the US. Beer is not a nootropic, but sex on the other hand.....
