Scientists report progress with brain-chip implants

Published: July 11, 2006

41878278_circ_203bWith a tiny electronic chip implanted in the Motor cortex of his brain, a 25-year-old man paralyzed from the neck down for five years has learned to use his thoughts to operate a computer, turn on a TV set, open email, play a video game and manipulate a robotic arm.

Two other patients with the implanted brain chips — one at the Rehabilitation Institute of Chicago — have advanced their brain-computer interface skills even further, although all movements are still rudimentary. One, a Massachusetts quadriplegic, unable to speak as a result of a stroke that destroyed her Brain stem, uses her thoughts to type messages using specialized software.

Paralyzed Man Thinks Robotic Devices into Motion

PROVIDENCE, R.I., July 12 — A man paralyzed from the neck down has been trained to control a computer cursor and manipulate robotic prostheses through a sensor implanted into his Motor cortex.

The 25-year-old man, a quadriplegic since a knife wound that transected his spinal cord, can open e-mail and operate a television — even while having a conversation — and exert rudimentary control over a multi-jointed robotic arm, reported John P. Donoghue, Ph.D., and colleagues, of Brown University here, and other centers, in the July 13 issue of Nature.

That Uppity Theatre Co. received a $10,000 grant from the Christopher Reeve Foundation, the foundation said Monday. The foundation awarded $850,439 in grants to 139 nonprofit organizations around the world as part of its Quality of Life program.

Since 1999, The Christopher Reeve Foundation (CRF) has awarded 1,073 grants totaling more than $8.5 million.

Scientists bridge’ spinal injury nerve gap

Published: July 11, 2006

Like linemen stringing an electric cable over a gorge, a research team co-directed by a Cleveland scientist has devised a way to coax nerve fibers to grow a “bridge” across gaps in rats’ damaged spinal cords.

The new technique, reported today in the Journal of Neuroscience, successfully re-established some neural connections and restored a “considerable” amount of movement in five of seven partially paralyzed rats, according to the researchers.

New Source of Multipotent Adult Stem Cells in Human Hair Follicles

xu_hair_sphere_am_journal_of_pathology_july_06Newswise — Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. If their approach to growing these cells can be scaled up and proves to be safe and effective in animal and human studies, it could one day provide the tissue needed by an individual for treating a host of disorders, including Peripheral nerve disease, Parkinson’s disease, and spinal cord injury.

“We are very excited about this new source of adult stem cells that has the potential for a variety of applications,” says senior author Xiaowei (George) Xu, MD, PhD, Assistant Professor of Pathology.

LA County agrees to settles medical malpractice suit for $890,000

Published: July 11, 2006

A man who claimed he received shoddy treatment for a spinal injury at Los Angeles County-USC Medical Center will receive $890,000 under a settlement approved Tuesday.

The county Board of Supervisors voted to approve the settlement of a medical malpractice lawsuit brought by Robert Maurer.

Neuroscientist awarded for spinal cord injury research

Published: July 11, 2006

A spinal cord injury scientist at Baylor College of Medicine in Houston was recognized for outstanding contributions to the advancement of spinal cord injury repair.

At the recent American Spinal Injury Association annual conference in Boston, Dr. Stephen Davies, assistant professor of neurosurgery at BCM, was presented with the Erica Nader Award, given every year in recognition of breakthrough research by an investigator in the field of spinal cord injury research.
