Key Features

Details

 

Alpha Omega’s AlphaProbe, has 4 Side Micro-contacts on the sides of the electrode shaft, 1 central microtip, and 2 Macro-contacts. 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 ok
