Advanced multi-channel electrode with enhanced data

Key Features

Alpha Omega’s AlphaProbe NeuroProbe, has 4 Side Micro-electrodes on the sides of the electrode shaft, 1 central micro tip, and 2 Macro-electrodes.

All 7 contacts can be switched between recording and stimulating enabling superior spatial resolution, rich data for analysis and enhanced flexibility in stimulation.

The AlphaProbe has one connector connecting to Alpha Omega’s Headstages, through which the signals from all 7 contacts are transmitted to the recording system.

  • 7 contacts in one electrode
  • Alpha probe workspace can work with HaGuide navigation software
  • Stimulation recommendation when working with HaGuide
  • Same dimensions as NeuroProbe
  • Dynamic Display of PSD/NRMS of the Micro contacts
  • Can be used in combination with NeuroProbes for additional data
