Linear Single-Shank 4-Channel Probe, 10 mm
Four sites clustered at one depth — isolation by amplitude ratio, not a depth profile
A single long shank with sites spread evenly down the shank, one per row, for a profile across depth. Among the 371 probe designs in the design space it sits at the bottom: 4 sites (5th percentile), 10 mm shanks (a common choice — 79 of 363), a 0.18 mm-deep site array (10th percentile), 750 sites/mm² (80th percentile) and a 0.18 mm³ neural interface (2nd percentile).
Large sites read a wider patch at lower impedance, suited to field potentials and multi-unit activity, spaced for a laminar profile. The long shank reaches deep targets.
Orders as a probe-plus-package assembly, in 11 package configurations. Silicon 50 µm thick. Z-coat available. Optical stimulation runs from a separate laser or LED source. Research use only.
