Neural Probes · A-Series (Polytrode & Tetrode)
Single-Shank 64-Channel Probe, 8 mm
Sites clustered rather than spread — polytrode and tetrode groups a sorter can separate
A single long shank with sites staggered in two columns so neighbouring sites see the same units. Among the 371 probe designs in the design space it is mid-range: 64 sites (a common choice — 68 of 369), 8 mm shanks (67th percentile of the 366 measured), a 3.19 mm-deep site array (92nd percentile), 547 sites/mm² (69th percentile) and a 0.99 mm³ neural interface (71st percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, packed densely enough to track a unit across neighbouring sites. The long shank reaches deep targets.
Orders as a probe-plus-package assembly, in 2 package configurations. Silicon 15 µm thick. Z-coat not available on this close-spaced poly layout. Research use only.
