Researchers at the University of Utah have developed a new, more precise way of placing microelectrodes on the surface of the brain to enable patients to turn thoughts into action. Led by Bradley Greger, a professor of bioengineering, the "Brain Carpet" as it's called, represents a "modest advance" in techniques already in use. The Brain Carpet makes use of smaller microelectrodes, and also employs many more than are usually used. The method involves sawing off the skull of the patient, then placing 32 electrodes about 2mm apart on the surface of the brain. Though they've conducted tests on just a handful of patients -- all epileptics -- the technique, they believe could also be used to help people control their prosthetic limbs much more effectively. The electrodes allow detection of the electric signals in the brain which control arm and hand movements. In the tests, patients have successfully controlled a cursor on a computer screen following the operation, and they see applications for brain-machine interface devices in the future. There's no word on when the Brain Carpet will move from the research to reality phase, but the group's findings have just recently appeared in the journal Neurosurgical Focus.
We'll be straight with you: it was pretty much love at first sight for us and dinosaur bones, and while we've always harbored a secret desire to someday acquire a real T-Rex fossil for our private collection, the LEDSAUR is probably our best shot at anything even close to that. Besides taking on that famous shape we love, this carnivorous piece of lighting is pretty stylish, with each of its vertebrae represented with an LED. The lamp is made of stainless steel, it's bendable, and it comes with a remote control. It's sadly only available in Japan for the time being, and runs between $115 and $270.
If you haven't had a chance to look at Resource Controller, Sean Schofield just put together a nice blog post on it. I've played with it a little bit on a recent project and really liked it. There are some pretty cool permissions things you can do in conjunction with Role Requirement too.
There's also an intro screencast that he points us to as well. Along with this shorter bit on thin controllers from RailsEnvy:
