Brainsight 2.3.4 is released for all users

We are happy to announce the release of Brainsight 2.3.4.

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 10.12.3 (Sierra).
  • We will not be supporting 10.9 for much longer; if you still use it, please upgrade.

Changes since version 2.3.3:

  • Numerous performance improvements in various places:
    • Improved 2D & 3D drawing performance in various places, especially with overlays on curvilinear reconstructions.
    • Better performance working with many landmarks or electrodes.
    • Faster region painting.
  • TTL triggers (ex: from our optional foot switch) can now be used during the coil/tool calibration procedure (useful for single operators).
  • Sample colour can now be changed from the Session Perform window.
  • Fixed a crash that could occur in the region paint window when choosing certain “isolation colours”.
  • Fixed various issues with the reconstruction+chamber clipping feature where it would previously sometimes hang, crash, or produce the wrong result.
  • Fixed a bug where electrode names would still be visible in 3D views even if the view was rotated such that they were in the back.
  • Fixed a bug where loading files with many electrodes would hang.
  • Fixed a bug where changing chamber properties would fail to redraw 2D views.
  • Connection tubes drawn between NIRS optodes in 3D views can now be clicked, which selects the two optodes at each end.
  • Image views are now able to draw characters from many more languages than before (ex: Japanese).
  • In addition to the CAD formats that can already be imported/exported (.stl, .ply, .dxf, .bscad), the .vtk polydata format is now also supported.
  • All the various parts of the user interface that show or accept numbers now use the localization settings from macOS System Preferences (ex: comma vs period for the decimal point).
  • Fixed miscellaneous bugs.


  • Brainsight 2.3.4 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’.
