Enhancing Brain Mapping

Introducing AlphaProbe - the cutting-edge solution that empowers brain mapping
with its unprecedented capacity to capture 5 times more crucial information.

 

The AlphaProbe has 4 directional Micro-contacts, 1 central micro-tip, and 1 Macro-ring electrode. This meticulously designed electrode provides:

Determine the relative position in the target structure with a single pass The AlphaProbe's directional side contacts detect relative positioning and nearby borders of DBS targets swiftly.

More easily confirm brain region transitions With AlphaProbe's 4 directional contacts, have greater confidence in the entry and exit of structures through LFP changes.

Superior spatial resolution & rich data for analysis All 6 contacts can be switched between recording and stimulating 

The AlphaProbe has one connector connecting to Alpha Omega’s Headstages, through which the signals from all 6 contacts are transmitted to the recording system.

HaGuide can simultaneously analyze all micro-contact data for real-time LFPs and background variations

Alpha Omega’s AlphaProbe, has the same profile as the current MER NeuroProbe.

  • Six 6 contacts in one electrode
  • AlphaProbe has same dimensions as the MER NeuroProbe
  • AlphaProbe workspace is compatible with HaGuide navigation software:
    • Visualize LFPs recorded from the micro tip and all four (4) side contacts
    • Identify how cellular activity changes across all contacts
    • View the entry and exit of the target from all contacts based on HaGuide's target detection algorithm
  • Ability to use up to two (2) additional NeuroProbes alongside the AlphaProbe (for Neuro Omega users only)
  • Type of recorded data:
    • Single-Unit Spike (SPK) from both the Micro and Macro contacts
    • Multi-Unit Activities from side contacts
    • Local Field Potentials (LFPs) from both the Micro and Macro contacts
