Tetrode/Linear 3-Shank 33-Channel Probe, 7 mm
Parallel shanks at a pitch fixed in fabrication — the same layer across several columns
Three long shanks side by side, spread for lateral coverage across columns, with tetrode groups along a linear run, isolation at set depths with a profile between. Among the 371 probe designs in the design space it is mid-range: 33 sites (73rd percentile), 7 mm shanks (63rd percentile of the 366 measured), a 0.52 mm-deep site array (29th percentile), 103 sites/mm² (35th percentile) and a 0.57 mm³ neural interface (45th percentile).
Mid-sized sites balance unit isolation against field-potential pickup, packed densely enough to track a unit across neighbouring sites. The long shanks reach deep targets.
Orders as a probe-plus-package assembly, in 27 package configurations, 5 of them microdrive-compatible. Silicon 15 or 50 µm thick. Z-coat available. Optical stimulation runs from a separate laser or LED source. Research use only.
