Symbiotic bacteria protect hunting wasps from fungal infestation

...ine. Female beewolves provision their larvae with paralyzed honeybees in brood cells in the soil. As part of this process, the researchers show, they use their antennae to deliver the symbiotic bacteria to the ceiling of the brood cell before finally closing off the cell. The larvae then take up the bacteria ...

Cyberkinetics, Case to develop system to help restore extremity function

...ll be, ultimately, to restore voluntary control of paralyzed muscles. "We are very excited to combine Cyberkin...tigators to advance restorative rehabilitation for paralyzed people. In addition, we are gratified that the NICHD has provided us the opportunity to develop our ...

MIT researcher finds neuron growth in adult brain

...isease or spinal cord injury, such as the one that paralyzed the late actor Christopher Reeve. "Knowing that neurons are able to grow in the adult brain gives us a chance to enhance the process and explore under what conditions -- genetic, sensory or other -- we can make that happen," said study co-author El...

Robotic joystick reveals how brain controls movement

... day is used routinely in rehabilitating partially paralyzed stroke patients and those with other brain injuries. To test the need for time in mastering muscle control, the research team designed a simple and short task. Fourteen healthy human subjects were asked to hold onto a robot-controlled joystick and k...

New approach to vaccine development provides potent, long-lasting immunity

... day is used routinely in rehabilitating partially paralyzed stroke patients and those with other brain injuries. To test the need for time in mastering muscle control, the research team designed a simple and short task. Fourteen healthy human subjects were asked to hold onto a robot-controlled joystick and k...

Neurons grown from embryonic stem cells restore function in paralyzed rats

...ect with muscles and partially restore function in paralyzed animals. The study suggests that similar technique... The cells were transplanted into eight groups of paralyzed rats. Each group received a different combination of treatments. Some groups received injections of ...

Brain-computer link lets paralyzed patients convert thoughts into actions

... computer and converted into actions -- enabling a paralyzed patient to perform basic tasks. In the 13 July ...tts man with a severe spinal cord injury, has been paralyzed from the neck down since 2001. After having the BrainGate sensor implanted on the surface of his bra...

Slow brain waves play key role in coordinating complex activity

...equency oscillations to control robotic devices in paralyzed patients. "This represents a paradigm shift in how we map brain function," said Berger. "As a neurosurgeon, I work within these very complicated cortical and subcortical areas where regions talk to each other, and there is a level of connectivity be...

Ebola-outbreak kills 5000 gorillas

... control effort was necessary or even possible has paralyzed large donors and major conservation organizations," said Peter Walsh, a co-author from Max Planck. "We are hoping that the starkness of our results will push some public or private donor to finally commit the two or three million dollars necessary to...

Neural networking nanotubes

...rve cells, control severe pain, or allow otherwise paralyzed muscles to be moved might one day be possible thanks to developments in materials science. Writing today in Advanced Materials, Nicholas Kotov of the University of Michigan, USA, and colleagues describe how they have used hollow, submicroscopic stran...

Computer with brain connections changing quality of life of paralyzed

...ing depression and quality of life are invalid for paralyzed people living in protected environments because most of the questions do not apply to the life of a paralyzed person. Special instruments had to be developed," says Niels Birbaumer, Ph.D., author of the study. ...

Conceptualizing a cyborg

...be able to return function to people who have been paralyzed by a spinal-cord injury, lost a limb, or in other ways. "Whether it is a prosthetic device or a disabled body function, the mind could regain control," says Smith. To create the interface, the team used a newly developed process of stretch growth ...

Rewarding fat rats

We all remember a time when we were paralyzed in the face of a tough decision. For animals in the natural world, making the right choice can mean the difference between life and death. When rats and other animals choose the thing that leads to a "reward," such as food, changes happen in the bo...

Robotic therapy helps restore hand use after stroke

..., although the affected hands were neither totally paralyzed nor unable to feel. Seven women and six men who had suffered a stroke at least three months prior participated in the pilot study using this robotic device. "Most spontaneous improvement in function occurs in the first three months after a stroke...

A 'traffic light' for neurons means 'go' for improving brain research

...s, perhaps restoring some function to the limbs of paralyzed patients. Finally, the technique could be useful in teasing out the largely unknown functioning of healthy brains. "One day we'd like to be able to understand the organization of the brain," Zhang says. "How do different types of cells communic...

Human stem cell treatment restores motor function in paralyzed rats

Rats paralyzed due to loss of blood flow to the spine returned to near normal ambulatory function six weeks after receiving grafts of human spinal stem cells (hSSCs), researchers from the University of California, San Diego (UCSD) School of Medicine report. The stu...
