Starting with macOS 15 Sequoia, macOS now requires that users grant permission to any application that uses the local network. Brainsight needs that permission granted for:

• Using network-based Polaris cameras like the Lyra and Vega (not for USB-based Polaris like Vicra)
• Using our NIRS device
• Using our Vet Robot device
• Using the NEURO PRAX EEG device
• Using the Axilum TMS-Robot and TMS-Cobot
• Using Brainsight’s network server feature

The first time Brainsight attempts to contact any such device, the following screen will appear:

Best to grant permission immediately. It *should* never ask again and work thereafter (though we have seen bugs in this area).

If you don’t grant permission immediately, or are having trouble connecting to the devices listed above: at the top left of the screen, click the Apple menu > System Settings > Privacy & Security > Local Network (you may need to scroll downwards to see it). In that screen, there should be a list of applications, including Brainsight. Make sure the switch on the right side of the list is enabled:

If Brainsight is still unable to access the network device, try switching the permission off then back on again, and reboot the Mac.

Early versions of macOS 15 Sequoia also had numerous bugs with this Local Network security feature, be sure to also update to the latest 15.x version.

We are happy to announce the release of Brainsight 2.5.8.

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 <https://support.apple.com/macos/upgrade>. 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), 12.7.6 (Monterey), 13.7.2 (Ventura), 14.7.3 (Sonoma), and 15.3.2 (Sequoia).
• Mac OS X 10.12 (Sierra) and earlier are unsupported. Support for 10.13 and 10.14 will be ending soon.

Changes since version 2.5.7:

• Fixed a bug in the ‘response:select-target-in-session’, ‘response:list-session-targets’, ‘response:create-sample’, ‘stream:sample-creation’, and ‘stream:sample-emg’ packets where the ‘coordinate-system’ field behaved as intended, but the ‘position’ field was always in Brainsight coordinates instead of the indicated coordinate system.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.8 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• 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.

• Mac OS X 10.12 (Sierra) and earlier are unsupported. Support for 10.13 and 10.14 will be ending soon.

Changes since version 2.5.6:

• Fixed a bug in the ‘create-target-at-location’ packet in the network protocol where the reported index path of the created target would (usually) be incorrect if there were any folders amongst the session’s targets.
• Changed the ‘create-target-at-location’ packet in the network protocol to allow the target position to be unspecified, in which case the target will be positioned at the current crosshairs position in the Session Perform window.
• When exporting curvilinear reconstructions to a file, they are now always coloured using the anatomical’s voxels. For curvilinears created from ROI, this is a bug fix because previously they weren’t being coloured at all. For curvilinears from overlays, this is a behaviour change as they were previously coloured from the overlay they were created from.
• Fixed miscellaneous bugs.

Download:

• Mac OS X 10.12 (Sierra) and earlier are unsupported. Support for 10.13 and 10.14 will be ending soon.

Changes since version 2.5.5:

• Brainsight can now act as a TCP/IP network server, and accept connections from one or more client applications. Clients can request that Brainsight perform certain actions, and Brainsight can inform clients when certain events occur. We provide documentation for the network communication protocol and sample Python code. (This feature requires at least macOS 10.14, and 10.15 for full functionality.)
• Oblique images (inline, inline 90, and perpendicular) use a better interpolation algorithm and thus now appear less grainy.
• Fixed a bug where long EMG channel names (from NEURO PRAX) were sometimes truncated in the legend.
• Added a warning if the NEURO PRAX measurement list is changed during a Brainsight session. This was never supported, and could corrupt data.
• Improved error messages when connection to a network-based Polaris fails.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.6 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• 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.

• Mac OS X 10.12 (Sierra) and earlier are unsupported. Support for 10.13 and 10.14 will be ending soon.

Changes since version 2.5.4:

• Made substantial improvements to Vet Robot tool calibration. The workflow is mostly the same except that you no longer need to identify the tool tip and shaft in both cameras simultaneously, you can instead do so in one camera at a time, which is helpful as the camera field of view is small and it can be hard to position a tool to be visible in both simultaneously. The algorithm that calculates the tool calibration is also much improved, giving more accurate tool calibrations.
• Improved Vet Robot tool-relative movement user interface to be more intuitive, and consistently move and rotate the tool around its axes: injection/retraction, left/right, forward/backward. Previously, the behaviour was not predictable.
• Vet Robot target reachability checks now have the option of checking that not only is the target itself reachable, but that a few millimetres deeper is also reachable. A new textfield in the Perform window allows setting this amount.
• Improved Vet Robot stereo calibration for small animal systems, to better cover the cameras’ field of view.
• Fixed a rare bug where Vet Robot stereo calibration could get stuck in an infinite loop.
• When importing targets from a text file, if the coordinate system name is set to “Relative”, the positions in the file can be interpreted as relative to another (already-existing) target.
• Fixed a bug where projects based on a SimNIBS .gmsh file could get the NIfTI sform and qform confused and result in an error message when invoking BabelBrain to perform a TMS simulation.
• Fixed a bug where Polaris tool tracking could sometimes show the subject tracker move with respect to the subject’s head. This was merely a visual glitch, and did not affect correctness.
• Improved performance working with many targets (example: big grids).
• Improved performance working with many electrodes (example: big EEG/NIRS caps).
• Improved performance opening .dxf files.
• The Polaris firmware version number is now shown in the Polaris Configuration window.
• In waveform views, when in staggered mode, you can now click a waveform to get a tooltip showing the channel name.
• Fixed a crash opening corrupt project files.
• Fixed a bug where recalibrating a NIRS block would program an incorrect version number into the block’s memory.
• Fixed a bug where the bullseye view would show a TMS coil in the background when a fUS tool was being used.
• Fixed a bug where the Vet Robot firmware version number would sometimes be displayed incorrectly.
• Fixed a bug where changing a sample’s EMG peak-to-peak value or its “contribute” checkbox would fail to refresh the sample’s colour in 2D and 3D views.
• Fixed a bug where changing the time index in a 4D overlay would sometimes fail to refresh 2D and 3D views.
• Fixed a bug where, if there were multiple surface reconstructions, changing the colour or other attribute of one would sometimes fail to refresh 3D views.
• Fixed a bug where, if there were multiple curvilinear reconstructions, changing the peel depth of one would sometimes fail to refresh 3D views.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.5 can be downloaded from our website here: <https://www.rogue-research.com/downloads>

• 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), 12.7.5 (Monterey), 13.6.7 (Ventura), and 14.5 (Sonoma).
• Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.3:

• Moved some user interface controls from the bottom to the top of the window, namely the 3D Crosshairs and Driver popup buttons. This gives more vertical space for images and makes the contents of the popup menu less likely to overflow.
• Added a new option in the Trigger Options window to allow creating samples even when the relevant Polaris tools are not visible (by default samples cannot be created when, for example, the coil tracker is not visible.)
• Now default to looking for SimNIBS 4.1 (newest at time of writing), instead of 4.0. If you have an older (or newer) version, adjust the path in Brainsight > Settings.
• Added a fourth set of tool-relative Vet Robot movement controls that only have buttons to inject and retract the tool. The controls that allow the more dangerous tool-relative rotations are now separated in a different pane.
• No longer allow Vet Robot to move to a marker-type target, only to trajectory-type targets. This is a safety precaution because, although markers technically have an orientation, it’s not displayed, and so the robot risks moving in an unexpected direction.
• Fixed a bug where Vet Robot subject registration would fail if the skull reconstruction was not watertight and consisted of several disjoint pieces and one of the initial registration landmarks was touching a secondary piece.
• For Vet Robot sessions, the default threshold range in the Validation step was tightened from 0.5 to 0.3 mm, reflecting recent improvements in system accuracy.
• Made various improvements for Axilum Robot / Cobot support:
  • An error message is now shown if the Cobot is not in MCP (manual control panel) mode.
  • Added functionality to switch Cobot sides.
  • The force sensor check procedure must now be redone if the coil is changed, or if two hours has elapsed.
  • Coil names are now partly anonymized, to no longer reveal if a sham coil is being used (to help with blind studies).
  • Extended the range of the contact sensor sensitivity.
• The Polaris Lyra is now configured to track at 30 Hz instead of 20 Hz.
• Fixed a bug where a bumps to a Polaris were not reported.
• Fixed a bug that could result in a failure to read some valid NIfTI files, for example those generated by BabelBrain.
• Fixed a bug where vector field arrows (for TMS simulation for example) sometimes did not display when then should have.
• Fixed a bug where 4D datasets with exactly 4 time components would be interpreted and drawn as vector fields.
• Added a new fUS transducer option for 3D Crosshairs shape.
• Added a new button next to the scene selection popup menu to quickly customize a view.
• A TMS coil is no longer shown in bullseye views when the selected tool calibration is fUS-type.
• Creating a surface/skin reconstruction is now about 25% faster.
• Creating a curvilinear reconstruction is now about 35% faster.
• Fixed various crashes that could occur opening corrupt files.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.4 can be downloaded from our website here: <https://www.rogue-research.com/downloads>

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 <https://support.apple.com/macos/upgrade>. 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.

Download:

• Brainsight 2.5.3 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• 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’.

• 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.
