Stimulation & Recording Products

Use our Front Ends to independently control up to 512 channels of stimulation and recording.


  • A complete Grapevine system includes Front End headstages that connect to a Grapevine processor
  • Signals are digitized in the Front Ends for low-noise neural recording
  • Fast-settle features allow for stimulus artifact rejection and rapid recording recovery following stimulation

Primary Use Cases

  • Stimulation
  • LFP
  • ECoG
  • Single/multi-unit activity
