SiliconProbeDrive

Easy to build, reusable silicon probe implant

Description

The SiliconProbeDrive is a chronic drive implant with a silicon probe for extracellular electrophysiology that includes drive body, skull part, Omnetic connector holder, and shuttle part. It has been used in freely moving mice running on a linear track, open field, and water maze. It was developed by Jyh-Jang Sun in Kloosterman lab at NERF.

Features

  • Channel count: 32 channels per drive

  • Lightweight: 2.1 grams

  • Assembled in a day

  • 7-mm travel distance

  • Reusable neural probe/implant.

To build a drive, you will need:

  • Print out the 4 STL files. We have tested grey resin and printed by Form 2 & 3 (Formlabs).

  • A custom screw (14.663mm-long M1.2; resolution: 250 µm per turn). The one from OpenEphys might work.

  • 2x 20G metal tubings (2mm-long) and 2X 23G metal tubings (8mm-long). Both could be ordered from Micro group.

  • 2x 6mm-long 1.2M screw; 4x 3mm-long 1.2M screw.

  • 4x female-male breakaway header pins.

  • A screwdriver. The one from OpenEphys might work.

  • A silicon probe for chronic recording. I have tested and assembled chronic probes from ATLAS Neuroengineering and Cambridge NeuroTech.
