Brown University A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces could help people with...

A thin, flexible electrode developed at the University of Michigan is 10 times smaller than the nearest competition and could make long-term measurements of neural activity practical at last. This kind of technology could eventually be used to send signals to prosthetic limbs, overcoming inflammation larger electrodes cause that damages both the brain and the electrodes. The main problem that neurons have with electrodes is that they make terrible neighbors. In addition to being...

(Ivanhoe Newswire) -- Through new technology scientists have a clearer understanding into the cellular mechanisms of neuronal networks. A new research has established a unique way of loading specific drugs onto a collection of electrodes and triggering its release into cultured neurons. Researchers at the University of Pittsburgh attempted to design an implant capable of detecting a number of neurological symptoms, including those associated with seizures, tiny electrodes are coated with a...

Physiological signals can nowadays be easily monitored with measurement devices implanted inside a living body. The object "“ animal or human "“ is barely aware of the presence of the implant. An example of a device implantable in humans is the pacemaker that has long since become standard treatment for heart patients. Researcher Jarno Riistama from Tampere University of Technology (TUT) believes that the next tech-savvy generation represents a potential customer base for new...

Scientists have developed a brain implant that essentially melts into place, snugly fitting to the brain's surface. The technology could pave the way for better devices to monitor and control seizures, and to transmit signals from the brain past damaged parts of the spinal cord. "These implants have the potential to maximize the contact between electrodes and brain tissue, while minimizing damage to the brain. They could provide a platform for a range of devices with applications in epilepsy,...

Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis. Neural electrodes must work for time periods ranging from hours to years. When the electrodes are implanted, the brain first reacts to the acute injury with an inflammatory response. Then the brain settles into a wound-healing, or...

U.S. scientists say brain signals controlling arm movement can be detected by using microelectrodes that are positioned on the brain, but don't penetrate it. The unique thing about this technology is that it provides lots of information out of the brain without having to put the electrodes into the brain, University of Utah Assistant Professor Bradley Greger, a co-author of the study, said. That lets neurosurgeons put this device under the skull, but over brain areas where it would be risky...

Word of the Day
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
