Miniature Microdrive 3-NRMD-

Miniature Microdrive

The Crist screw style Microdrive for use with chronically implanted electrodes in freely moving animals. These drives can be used in animal species from cats to non-human primates. This Microdrive allows for repositioning of the electrode as needed. The Microdrive is attached to the grid inside the recording chamber and can hold 1 to 3 electrodes per drive. All electrodes attached to a single Microdrive will advance or retract at the same time. Multiple Microdrives can be mounted inside the grid. Each full revolution of the screw is 250 microns.

Features and Benefits:

  • Each Drive can be configured to move up to 3 electrodes simultaneously
  • Multiple drive can be mounted on the grid within the chamber
  • One revolution of the screw advances or retracts the electrode 250 microns
  • Exceptionally useful for fine adjustments needed on a long term basis

General specifications:

  • Symmetric or asymmetric foot pattern available
  • One to three electrode carrier block
  • 15.24 mm drive distance (15 240 microns)
