ECoG 64-Channel Grid
Polyimide substrate that follows the cortical surface — epidural or subdural, 4 to 256 sites
A thin polyimide film that lies on the cortical surface and follows its curvature and movement, carrying small sites that read a local patch at high impedance, on a long cable for routing to the connector. Among the 56 grid designs in the design space it is in the upper quartile: 64 sites (a common choice — 9 of 55), a 12 mm site-array span (84th percentile), 9.35 sites/mm² (80th percentile) and a 6.8 mm³ neural interface (34th percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 40 mm cable. Research use only.
