Buzsaki 2-Shank 32-Channel Probe, 10 mm
Silicon 3D probe platform — several 32-site 2D arrays, 64 to 256 channels, recording and stimulating

Two long shanks side by side, spread for lateral coverage across columns, with sites staggered near the edges of each tip — the Buzsaki layout for spike discrimination. Among the 371 probe designs in the design space it is mid-range: 32 sites (a common choice — 155 of 369), 10 mm shanks (a common choice — 79 of 363), a 0.95 mm-deep site array (52nd percentile), 37 sites/mm² (16th percentile) and a 1.02 mm³ neural interface (72nd percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation. The long shanks reach deep targets.
Orders as a probe-plus-package assembly, in 19 package configurations, 2 of them microdrive-compatible. Built for the Matrix Array platform: this 2D array installs in a Matrix package slot and is not assembled in other packages. Silicon 50 µm thick. Z-coat available. Research use only.
