Professor Ellis Meng of the USC Viterbi Department of Biomedical Engineering and Michelson Center for Convergent Bioscience said that the performance of the new polymer - based material is on par with
microwires in terms of recording fidelity and sensitivity.
In addition to inflammation, previous microelectrode brain implants made of silicon or
microwire have caused neuronal death and glial scarring, which is damage to connective tissue in the nervous system.
In addition, the polymer - based material, called Parylene C, is less invasive and damaging to surrounding cells and tissue than previous microelectrode arrays comprised of silicon or
microwires.
The study described in the second paper used groups of three or four rats whose brains were interconnected via
microwire arrays in the somatosensory cortex of the brain and received and transmitted information via those wires.
Stimulation using
microwires presents a novel opportunity to improve selective and natural activation of neuronal circuits in the human brain.
