Heptagon Acoustic Tweezer repairs damaged nerves

acoustictweezer

Miniaturized ultrasonic device capable of capturing and moving single cells and tiny living creatures.

University of Glasgow researchers have devised a Heptagon Acoustic Tweezer which makes use of resonance for manipulating matter. This sonic tweezer uses acoustic force to build cell matrices with the possibility of repairing injured nerves.

Scientists discover mechanism that could regrow damaged nerves

spinal-cord

The discovery could lead to developing a drug that can trigger regrowth of damaged nerves.

Spinal cord injuries are currently irreparable. Most people who suffer from such an injury never fully recover, and many end up with partial or even full paralysis. Although we’ve made great strides in understanding how spinal injuries damage nerves and how we might fix the spinal cord in the future, and even how those patients can cope in the meantime, we still don’t know how to repair the nerves themselves when such an injury occurs. However, scientists at Imperial College London have recently discovered a mechanism that allows them to repair, and even regenerate, nerves in the central nervous system after a spinal cord injury.

Tiny Implants Connected To Nerve Cells Could Allow Greater Control Of Prosthetics

myotubes_x220

Muscle cells (shown here) are grown on a biological scaffold.

A novel implant seeded with muscle cells could better integrate prosthetic limbs with the body, allowing amputees greater control over robotic appendages. The construct, developed at the University of Michigan, consists of tiny cups, made from an electrically conductive polymer, that fit on nerve endings and attract the severed nerves. Electrical signals coming from the nerve can then be translated and used to move the limb.

Chronic Pain Can Be Treated With Tiny Injectable Implants

Chronic Pain Can Be Treated With Tiny Injectable Implants

RFID technology allows neural stimulators to get really small.

A tiny injectable implant, smaller than a grain of rice, might one day take the place of large neural stimulators used to treat chronic pain and other neurological disorders. The novel device, under development by MicroTransponder, a Dallas-based startup, owes its small size to the use of RFID (radio-frequency identification) technology like that used to tag clothes to prevent shoplifting.

Infrared Light Could Bring Music To The Deaf

Infrared Light From Xbox

Scientists have accidentally discovered that infrared light can stimulate neurons in the inner ear like sound waves do. While trying to “weld” nerves with heat from a laser, surgeons found that the light could stimulate the ear nerves extremely precisely. A research team led by Claus-Peter Richter at Northwestern University in Chicago decided to explore this idea further.

Rewiring The Brain May Help Treat Paralysis

Rewiring The Brain May Help Treat Paralysis 

 Paralyzed monkeys regained the ability to move their wrists when their nervous systems were rewired.

Rerouting electrical signals around damaged nerves may one day help treat paralysis.  A pair of partially paralyzed monkeys regained the ability to move their wrists when researchers wired individual neurons directly to the monkey’s arm muscles, according to a study published online in Nature on Wednesday.

Hand Transplant Patient Shows Signs Of Sensory Recovery

Hand Transplant Patient Shows Signs Of Sensory Recovery 

Activation of the left cerebral hemisphere during sensory stimulation of the transplanted right palm.  

Four months after a successful hand transplant — 35 years after amputation in an industrial accident at age 19 — a 54-year-old man’s emerging sense of touch is registered in the former “hand area” of the his brain, says a University of Oregon neuroscientist.
