Brainsight 2.3.3 is released for all users

Dear Brainsight user,

We are happy to announce the release of Brainsight 2.3.3.

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

Minimum requirements:

  • Mac OS X 10.9 Mavericks or later is required. For a free update, visit <>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against OS X 10.10.5, 10.11.6, and 10.12 (Sierra).
  • We will not be supporting 10.9 for much longer; if you still use it, please upgrade.

Changes since version 2.3.2:

  • Grids can now be snapped to a reconstruction surface. Additionally, for trajectory-type grids, the grid nodes can be oriented tangential to the same or another surface. In case the automatic snapping needs tweaking, individual grid nodes can now be moved/reoriented.
  • Samples are now indicated in NIRS waveform views with vertical lines that show when each sample occurred.
  • The ‘Save As…’ feature has been restored, but only in macOS 10.12 Sierra, where Apple has fixed a bug that affected Brainsight.
  • Trying to enable Polaris tracking while a NIRS acquisition is in progress will now warn first.
  • Fixed a crash that sometimes occurred when closing a session perform window.
  • Fixed several compatibility issues with macOS 10.12 Sierra.
  • Fixed miscellaneous bugs.


  • Brainsight 2.3.3 can be downloaded from our website here <>
  • You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter Serial Number’.


Thank you,

The Rogue Research Team
