Latest Multielectrode array Stories
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.
Through new technology scientists have a clearer understanding into the cellular mechanisms of neuronal networks.
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.
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.
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.
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.
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
