A compact, self-contained sensor recorded and transmitted brain activity data wirelessly for more than a year in early stage animal tests, according to a study funded by the National Institutes of Health. In addition to allowing for more natural studies of brain activity in moving subjects, this implantable device represents a potential major step toward cord-free control of advanced prosthetics that move with the power of thought. The report is in the the Journal of Neural Engineering.
Scientists at the University of Edinburgh have identified a protein crucial for maintaining the health and function of the segment of nerve fibres that controls transmission of messages within the brain.The study, published in the journal Neuron, could help direct research into neuro-degenerative disorders, in which electrical impulses from the brain are disrupted. This can lead to inability to control movement, causing muscles to waste away.
