Linear 8-Shank 256-Channel Probe, 8 mm
Sites spread along the shank — linear and edge layouts for depth profiling
Eight long shanks side by side, spread for lateral coverage across columns, with sites spread evenly down each, one per row, for a profile across depth. Among the 371 probe designs in the design space it is in the upper quartile: 256 sites (99th percentile), 8 mm shanks (67th percentile of the 366 measured), a 1.56 mm-deep site array (75th percentile), 77 sites/mm² (31st percentile) and a 2.7 mm³ neural interface (94th percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, spaced for a laminar profile. The long shanks reach deep targets.
Orders as a probe-plus-package assembly, in 5 package configurations. Silicon 15 µm thick. Z-coat available. Research use only.
