Brainsight 2.4.7 is released for all users

We are happy to announce the release of Brainsight 2.4.7.

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

Minimum requirements:

  • Mac OS X 10.11 El Capitan 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 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), and 11.1 (Big Sur).
  • Mac OS X 10.11 (El Capitan) and 10.12 (Sierra) are now only lightly tested.
  • Mac OS X 10.10 (Yosemite) and earlier are unsupported.

Important Compatibility Note:

  • If you are already using the Brainsight 2.5 beta, don’t install this version.

Changes since version 2.4.6:

  • Added support for the new macOS 11 Big Sur, notably communication with Polaris cameras now works.
  • Numerous changes to Axilum Robotics support:
    • A new feature in the Session Perform window now allows visiting a sequence of targets, pausing for a specified number of TMS pulses, with a specified duration between them, and then moving to the next target.
    • The “Align” buttons have changed behaviour in several notable ways: They now only act on the sole selected target. They no longer can be used for a folder of targets.
      • They now move in whatever path is necessary to ultimately reach the target and always descend the coil to contact the skin. (Previously, there were two behaviours: if the coil was already on the skin, they would only try to slide along the skin, and if the target was too far, no movement would result at all. If the coil was in orbit, they would align above the new target, but not descend to the skin.)
      • To signal this behaviour change, the buttons have been renamed from “Align” to “Move”.
      • The “Stop” button now moves the robot arm away from the subject’s head, if it was in contact.
    • Closing a session window now warns if you are connected to a robot, instead of just closing.
    • Added tooltips to most of the Axilum-related buttons, to help understand what they each do.
  • Added a second kind of subject registration for Vet Robot sessions. Instead of using two landmarks and the laser grid, you can now use three or more landmarks for a classic rigid body registration. This requires being able to accurately locate such landmarks both on the anatomical scan and in the camera images.
  • The Targets window now allows importing target names and coordinates from a text file.
  • Fixed a bug where older documents sometimes failed to convert to the newest format with the message “crosshairs is a required value”.
  • Fixed a bug where the “switch” input on the IOBox was triggering from high to low voltage instead of low to high voltage, resulting in presses of the foot switch being recognised upon releasing the pedal instead of upon depressing the pedal.
  • Fixed a crash that could occur choosing some colours in the ROI window.
  • Fixed a crash importing some SPM12 .mat files.
  • Fixed a crash on macOS 10.14 and older that could occur if a TTL trigger was received while editing the peak-to-peak value in the Inspector > Motor Maps window.
  • Fixed various bugs with macOS dark mode, where some things were drawn with incorrect or illegible colours.
  • Fixed a bug where landmark/electrode names that contained two parts, like “LA43-LA44”, would only have the first half spoken.
  • The Session Validation window now allows choosing the crosshairs shape, like most other steps in the Session window.
  • Fixed an old bug where the first use of the Apple Remote after booting the Mac resulted in the first button press being reacted to twice.
  • Fixed a bug where the Apple Remote up and down buttons did not work on macOS 10.13 and newer.
  • Fixed a bug where the Apple Remote did not work at all on macOS 10.15 and newer.
  • Fixed miscellaneous bugs.
