TL;DR: An extensible 3D-platform of thin film flexible microscale ECoG arrays appropriate for Brain-Computer Interface (BCI) application, as well as monitoring epileptic activity, is presented.
Journal ArticleDOI
The effect of micro-ECoG substrate footprint on the meningeal tissue response
Amelia A. Schendel,Michael W. Nonte,Corinne R. Vokoun,Thomas J. Richner,Sarah K. Brodnick,Farid Atry,Seth Frye,Paige Bostrom,Ramin Pashaie,Sanitta Thongpang,Kevin W. Eliceiri,Justin C. Williams +11 more
TL;DR: Data suggest that an open architecture device would be more ideal for neural recording applications, in which a low impedance path from the brain to the electrode sites is critical for maximum recording quality.
