New brain implant for neural recording provides more data, less tissue damage

23-Mar-2020
KEY POINTS FROM ARTICLE:

Device created to help record activity in thousands of individual neurons.
It could be used for research or with prosthetics.
It is capable of recording more data while being less intrusive than other options.
Design is completely different from any existing high-density recording devices.
Can simultaneously record different brain regions at different depths in any 3D arrangement.
Made with microwires encased in biologically-safe polymer.
These are bundled by metal collar, then finished with a silicon chip for recording.
First testing successful with retinal cells from rats and a 138-wire array.
Also a success when tested in brains of living mice, using 135-251 arrays.
"Electrical activity is one of the highest-resolution ways of looking at brain activity".
Research by team from Stanford University, published in Science Advances.

Thousands of single-neuron activities can be recorded as successfully tested in mice
