Brainsight 2.5.3 is released for all users

We are happy to announce the release of Brainsight 2.5.3.

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 14.3 (Sonoma).
  • Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.2:

  • Brainsight can now simulate the acoustic effect of transcranial focused ultrasound (fUS) at a target location. It does this by interacting with BabelBrain, a third party software that must be installed separately. The Targets window now allows invoking BabelBrain, wherein simulation parameters can be set. The resulting simulation appears overlaid in 2D and 3D images, and can be customized from the Inspector window.
  • When writing to our .txt file formats, we now use slightly different coordinate system names for NIfTI files, which may require updating code that reads these files. The coordinate system name now includes whether it’s from the file’s sform or qform. So, for example, where we used to use a string like “NIfTI:Scanner” we now use “NIfTI:Q:Scanner”. For this reason, exported .txt files increased from version 13 to 14, and .txt files created by streaming increased from version 6 to 7.
  • Improved performance when creating hundreds of samples. There should be noticeably less latency between the trigger that creates a sample and its appearance in the application.
  • Substantially improved accuracy of Vet Robot subject registration, thus improving accuracy results overall.
  • Fixed a bug, introduced only in 2.5.2, where selecting two or more samples was not showing the average waveform for EEG and NIRS views (but was for EMG views).
  • Fixed a bug where EMG waveform views sometimes did not show the visual indication (crosshatching) of when a waveform has exceeded the EMG pod device’s maximum range of 2.25 mV.
  • Fixed a bug in EMG views where the line indicating the EMG latency would sometimes not redraw after the time range was changed (with the green vertical bars).
  • Fixed a bug where electrodes could still be clicked in 3D views, even when all electrodes were hidden.
  • Fixed miscellaneous bugs.


  • Brainsight 2.5.3 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,
