Linear 8-Shank 256-Channel Probe, 5 mm
Sites spread along the shank — linear and edge layouts for depth profiling
Eight mid-length 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 mid-range: 256 sites (99th percentile), 5 mm shanks (a common choice — 107 of 363), a 1.1 mm-deep site array (57th percentile), 110 sites/mm² (35th percentile) and a 2.09 mm³ neural interface (92nd percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, spaced for a laminar profile. The mid-length shanks reach structures a few millimetres down.
Orders as a probe-plus-package assembly, in 5 package configurations. Silicon 15 µm thick. Z-coat available. Research use only.
