Artificial alternative to spinal fusion
Artificial disc replacement as good or better than spinal fusion surgery
Feb. 26,
2009 -- Spine surgeons at theSchool of Medicine and other U.S. centers are reporting that artificial disc replacement works as well and often better than spinal fusion surgery. The two procedures are performed on patients with damaged discs in the neck.

Brain-computer interfaces may help move limbs
Brain implants may help stroke patients overcome partial paralysis
Nov. 11,
2008 -- Scientists have shown for the first time that neuroprosthetic brain implants may be able to help stroke patients with partial paralysis. Researchers found that implants known as brain-computer interfaces (BCI) may be able to detect activity on one side of the brain that is linked to hand and arm movements on the same side of the body. They hope to use these signals to guide motorized assistance mechanisms that restore mobility in partially paralyzed limbs.

Teenager moves video icons by imagination
United Press International
and 2 others
Oct. 11,
2006 -- A U.S. boy has become the first teenager to play a two-dimensional video game using only the signals from his brain to make movements.
WUSTL researchers led by neurological surgery professor Eric Leuthardt and biomedical engineering professor Daniel Moran say the boy's achievement might lead to creation of biomedical devices that can control artificial limbs, enabling the movement of a prosthesis by just thinking about it.

devised a technique on humans that for the first time shows just what the brain does when the skull accelerates
Space Daily
Dec. 16,
2005 -- Mechanical engineers at WUSTL along with collaborators, have devised a technique using MRI technology that shows how the human brain reacts when the skull accelerates. The research shows that as the skull accelerates, the numerous vessels, membranes and nerves at the base of the brain, try to pull away, from the spine leading to a significant deformation in the front of the brain. Philip Bayly, Ph.D., Lilyan and E. Lisle Hughes Professor in Engineering, discussed the group's findings Nov. 10, 2005, at the annual meeting of the National Neurotrauma Society in Washington, DC.

Computers obey brain signals from paralyzed people ... and our reporter, too
Associated Press
May 4,
2005 -- Scientists are working on early steps toward a complex but straightforward technological goal: to use electrical signals from the brain as instructions to computers and other machines, allowing paralyzed people to communicate, move around and control their environment literally without moving a muscle. When surgeons at Washington University in St. Louis, in cooperation with Wolpaw, placed tiny electrodes on the surface of the brains of four people recently, they achieved accuracies of 74 percent to 100 percent in an electronic game with just three to 24 minutes of training.

Patients play by power of thought
Sydney Morning Herald (Australia)
and 20 others
June 16,
2004 -- Using thought alone and with electrodes placed on the surface of the brain, four volunteers were able to control a simple video game, U.S. researchers report. Simply by thinking the word "move," the volunteers played the game.
"We are using pure imagination. These people are not moving their limbs," said Eric Leuthardt, a neurosurgeon at the School of Medicine who worked on the study. Writing in the Journal of Neural Engineering, Leuthardt and Daniel Moran, assistant professor of biomedical engineering at the School of Medicine, said the patients learned in minutes how to control a computer cursor.
