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 mid-sized sites that trade local detail for signal, on a long cable for routing to the connector. Among the 56 grid designs in the design space it sits at the top: 64 sites (a common choice — 9 of 55), a 18 mm site-array span (91st percentile), 0.2 sites/mm² (18th percentile) and a 166 mm³ neural interface (91st percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 50 mm cable. Research use only.
