Brainsight 2.5.2 is released for all users

We are happy to announce the release of Brainsight 2.5.2.

Before proceeding with this update, please read the following important information.

Minimum requirements:

  • macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7 (Monterey), 13.6 (Ventura), and 14.0 (Sonoma).
  • Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.1:

  • Added calculation and display of EMG latency using the SHTE algorithm (by Šoda, Vidaković, Lorincz, Jerković, and Vujović). The Perform and Review windows now have a new optional table column that can show the latency for each sample. In addition, waveform views now draw a vertical line at the latency time. This line can be dragged to adjust the automatically computed value if it seems incorrect. Latency can also be streamed to a .txt file from the Perform window, and exported to a .txt file from the Review window.
  • Each surface-type reconstruction can now be configured to participate in overlay blending or not. If the option is off, overlays will never be blended on that surface. If the option is on, overlays will be blended atop that surface, provided the overlay is enabled in the Inspector window (as usual). This option is off by default.
  • A tool calibration’s 4×4 matrix can now be exported to a MINC .xfm text file.
  • The Vet Robot can now be moved relative to the currently used tool.
  • The Session Polaris window now allows selecting the Polaris, and also has a button in bring up the Polaris Configuration window.
  • More windows now have the option of showing the crosshair’s numerical coordinates (at the bottom right).
  • Fixed a bug where some projects with corrupt NIRS data would fail to load.
  • Fixed a longstanding bug where the brightness/contrast slider did not work in the Curvilinear From Overlay and Surface From Overlay windows when an overlay was used as the source of the reconstruction.
  • Fixed a bug where Brainsight would not automatically connect to a Polaris, even if it was detected.
  • Fixed a bug where some image views would stop drawing after Brainsight was running in the background.
  • Fixed a crash creating motor maps on old Macs with Nvidia GPUs.
  • Improved performance creating motor maps on Macs with Apple Silicon processors.
  • Fixed several crashes that could occur when opening corrupt files of various formats.
  • Fixed miscellaneous bugs.


  • Brainsight 2.5.2 can be downloaded from our website here: <>
  • You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.
  • You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.


  • Please report any and all bugs, feedback, suggestions, etc. to <> or by phone at +1-866-984-3888 (Canada & USA) or +1-514-284-3888.

Thank you,
