The Mets claim that Gomez has been pulled to limit his games, not because a trade is imminent. That doesn't make much sense, though. Obviously it's important to keep players healthy but wouldn't the Mets relish the chance for Gomez to play in an intense, playoff-type atmosphere if he was going to be part of their own pennant push in 2008?Laser Controlled Humans Closer to Reality
Flashes of light may 1 daytime be used to control the people brain, and that daytime fair got a lot closer.
Using lasers, researchers at the MIT Media Lab were skillful to refresh a specific set of neurons in a monkey’s head. Though the technique has been secondhand to control and explore neural circuits in fish,cheap timberland shoes, flies and rodents,tennis rackets for beginners, this is the premier time the much-hyped technology has ever been accustomed in primates.
“It paves the way because new therapies that could target a digit of psychiatric disorders,” said MIT neuroscientist Ed Boyden,five finger classic, who led the research with postdoctoral companion Xue Han. “This is very exciting from a translational standpoint.”
The prettiness of this optogenetic technique is its specificity. By using a medley of lasers and genetic engineering, scientists can control, to the millisecond, the firing of a specific class of neurons, granting them apt needlepoint problematic cells and circumferences while leaving innocent bystanders single, thus minimizing potential side effects.
Viruses are engineered to infect neurons with a special type of outlet, originally discovered in algae, which is sensitive to blue light. Once a blue laser shines ashore the infected neurons, the channels snap open, ions rush into the cell, and the neuron fires.
Crucial to the technique is that the virus is only injected into a very small chapter of the brain, and only a certain class of neurons, once infected, really turn the channel on. The keen laser beam further zeros in on a small part of the brain. This precise intention is in contrast to present techniques, such for drugs and electrodes, either of which have a many broader reach.
The optogenetic method was pioneered in 2005 along Boyden and Karl Deisseroth at Stanford University and has since been used to comprehend how circuits of neurons control various behaviors, such as studying in mice and predator escape in fish. But until now,earthkeepers chukka, scientists had not demonstrated the technique in primates ― a shake essential for amplifying therapeutic uses for the technology in humans.
Boyden’s new research, published Wednesday in Neuron, demonstrates no only that the technology goes in primates, but likewise that it is safe. The rhesus macaques received multiple circulars of injections and laser stimulations over the course of eight or nine months without damaging the neurons or activating the brain’s immune system, one manifest care when viruses are comprised.
“Many disorders are associated with changes in specific cell types,” said Boyden. “For medical intentions, you want to affect certain cells, yet you absence to leave regular cells intact. The ability to use light to corner specific cells at times with quite precise timing could in conviction allow current therapies.”
Future petitions could involve using light-emitting neural prosthetics to replace the electrodes used in deep brain stimulation,sale on tory burch flats, which currently activate or pacify a spacious range of neurons. Deep brain stimulation has shown agree in treatments of Parkinson’s disease, epilepsy and depression, but it has a number of side effects, stemming in part from its absence of specificity.
