Edge 8-Shank 128-Channel Probe, 5 mm
Sites spread along the shank — linear and edge layouts for depth profiling
Eight mid-length shanks side by side, closely spaced for coverage within one structure, with sites along the shank's edge, closest to the tissue the probe faces. Among the 371 probe designs in the design space it is mid-range: 128 sites (96th percentile), 5 mm shanks (a common choice — 107 of 363), a 0.77 mm-deep site array (44th percentile), 158 sites/mm² (43rd percentile) and a 0.99 mm³ neural interface (71st 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 10 package configurations, 3 of them microdrive-compatible. Silicon 15 µm thick. Z-coat available. Research use only.
