Researchers of the Department of Biosystems Science and Engineering of ETH Zurich were able to measure the speed of neuronal signal conduction along segments of single axons in neuronal cultures by using a high-resolution electrical method. The bioengineers are now searching for plausible explanations for the large conduction speed variations. To write this little piece of text, the brain sends commands to arms and fingers to tap on the keyboard. Neuronal cells with their cable-like...

(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...

Tiny electrodes have been coated with a drug-loaded polymer in an attempt to design an implant capable of detecting a number of neurological symptoms, such as those associated with an epileptic seizure, and treating them simultaneously. In a study published today, 2 June 2011, in IOP Publishing's Journal of Neural Engineering, researchers have developed a novel technology to precisely modulate individual neurons in rats, allowing the molecular, neuronal, and circuit functions to be analysed...

Demonstrating an important milestone for the longevity and utility of implanted brain-computer interfaces, a woman with tetraplegia using the investigational BrainGate* system continued to control a computer cursor accurately through neural activity alone more than 1,000 days after receiving the BrainGate implant, according to a team of physicians, scientists, and engineers developing and testing the technology at Brown University, the Providence VA Medical Center, and Massachusetts General...

 Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit 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...

University of Reading scientists say an unlikely source - a blob of rat brain cells - controls a robot, a process that could provide clues into diseases like Alzheimer's. Meet Gordon, the world's first robot controlled exclusively by living brain tissue. The groundbreaking experiment of the neuron-powered machine explores the vanishing boundary between natural and artificial intelligence. One of the lead researchers said it sheds light on the fundamental building blocks of memory and...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
