Injectable Nanowires Monitor Mouse Brains for Months

Injectable Nanowires Monitor Mouse Brains for Months

Want to understand what happens to the brain as it ages, or figure out how people learn to recognize faces? Neurologists asking such questions, or struggling to deal with brain degeneration caused by Parkinson’s and Alzheimer’s, might get some insight from detailed observations of the brain’s circuitry over time. But so far, such information has been hard to come by. Now researchers at Harvard have shown that they can track brain activity, at the level of individual neurons, for months at a time, using a tiny electronic mesh that can be injected directly into the brain. A group led by Charles Lieber , a chemistry professor at Harvard, reports in this week’s Nature Methods that they were able to record the neural activity of mice over eight months, long enough to see how the animals’ brains changed as they entered the mouse version of middle age. “This really brings us the ...
