Linear 4-Shank 64-Channel Probe, 5 mm
Sites spread along the shank — linear and edge layouts for depth profiling
Four mid-length shanks side by side, 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: 64 sites (a common choice — 68 of 369), 5 mm shanks (a common choice — 107 of 363), a 0.78 mm-deep site array (47th percentile), 54 sites/mm² (21st percentile) and a 1.3 mm³ neural interface (81st percentile).
Large sites read a wider patch at lower impedance, suited to field potentials and multi-unit activity, spaced for a laminar profile. The mid-length shanks reach structures a few millimetres down.
Orders as a probe-plus-package assembly, in 8 package configurations. Silicon 15 or 50 µm thick. Z-coat available. Research use only.
