  • (2024-10-30) An atlas for the prairie vole Microtus ochrogaster has been added to BrainGlobe, by Adam Tyson

    Prairie voles are a valuable model species for studying social interaction due to their characteristic pair-bonding behavior. The brain of this species is structured similarly to the mouse and is only 30% larger, meaning it is particularly well suited to methods to map brain anatomy and function using light microscopy, such as light-sheet fluorescence microscopy and serial section two-photon microscopy.

  • (2024-08-09) An Atlas for the regenerative Ambystoma mexicanum (axolotl) has been added to BrainGlobe, by Saima Abdus, Alessandro Felder, David Perez-Suarez

    Amphibians have long captivated human’s interest. An unusual amphibian amongst these is the Axolotl (Ambystoma mexicanum), which is sometimes used as a model organism for regeneration. In 2021, Lazcano et al. created a magnetic resonance imaging (MRI) atlas of the juvenile axolotl brain. The axolotl atlas enables researchers to gain better insights into the processes underlying central nervous system (CNS) regeneration.

  • (2024-08-02) A mouse brain atlas with barrel field annotations has been added to BrainGlobe, by Adam Tyson, Axel Bisi

    Bolaños-Puchet et al., 2024 recently published annotations of 33 barrels and barrel columns of the mouse isocortex in the Allen Mouse Brain Common Coordinate Framework. The Allen Mouse Brain Atlas (and particularly its Common Coordinate Framework) has been key to advances in computational neuroanatomy in the adult mouse. However, this atlas does not contain detailed annotations of the barrel cortex, which is the dominant topographically represented whisker-related area of the primary somatosensory cortex. The barrel cortex is a highly relevant system to study as mice are nocturnal, tunnel-dwelling animals that largely rely on their whiskers to survive. These annotations allow researchers to much more precisely localise features of interest within specific barrel columns vs. other barrels, within barrels vs. septa, for example, rather than the barrel field as a whole.

  • (2024-07-31) New brainmapper napari widget released, by Adam Tyson

    One common use of BrainGlobe tools is to analyse the distribution of cells in a whole brain image. This process involves first detecting cells using cellfinder and then registering (aligning) the data to a BrainGlobe atlas using brainreg. The detected cell positions must then be transformed from the coordinate space of the raw data to the coordinate space of the atlas for analysis.

  • (2024-06-21) An atlas for the Blind Mexican Cavefish has been added to BrainGlobe, by Alessandro Felder, Robert Kozol

    Kozol et al, 2023 recently published a brain atlas of the blind Mexican cavefish Astyanax mexicanus. This species is interesting from an evolutionary point of view, due to divergent phenotypes (surface- and cave-dwelling) that can be hybridised in the lab. Surface-dwelling populations have retained their eyesight, while cave-dwellers have not. The cavefish brain atlas allows us to understand how brains of a single species have changed anatomically and functionally as part of their adaptations to the environment.

  • (2024-06-03) Cellfinder version 1.3.0 is released!, by Igor Tatarnikov

    We are excited to announce that a new version of cellfinder has been released.

  • (2024-05-16) BrainGlobe version 1.1.0 is released!, by Adam Tyson

    A new version of the BrainGlobe metapackage has been released following updates to lots of BrainGlobe tools (details below).

  • (2024-02-14) bg-atlasapi and bg-atlasgen have merged under a new name, by Will Graham

    bg-atlasapi and bg-atlasgen have merged into a single package, now called brainglobe-atlasapi. brainglobe-atlasapi now provides the same API that bg-atlasapi provided, in exactly the same way - all that needs to happen is a name change in your scripts.

  • (2024-02-08) imio will be merging into brainglobe-utils, by Will Graham

    The imio package will be absorbed into brainglobe-utils as a submodule, so will no longer be receiving standalone updates. This decision was made because:

  • (2024-01-24) bg-space has been renamed, by Will Graham

    The “bg” prefix that a number of BrainGlobe tools carry is not very distinctive nor informative, so we are rolling out minor name changes to a lot of our packages that contain this prefix. We are also taking this opportunity to bring these tools into line with our developer guidelines for automatic deployment, tooling, and testing.

  • (2024-01-08) BrainGlobe version 1 is here!, by Will Graham

    Following our series of incremental updates to a number of BrainGlobe tools, we are pleased to announce that BrainGlobe version 1 has been released today! Users can now enjoy:

  • (2024-01-02) cellfinder-core and cellfinder-napari have merged, by Will Graham

    BrainGlobe version 1 is almost ready, and the next stage of its release journey is the merging of the “backend” cellfinder-core and cellfinder-napari packages into one. We had previously migrated the cellfinder data analysis workflow into the new brainglobe-workflows package, as part of our efforts to separate “backend” BrainGlobe tools from common analysis pipelines. This means that there is no longer any need to keep the “backend” package (cellfinder-core) and nor the visualisation plugin (cellfinder-napari) stored in separate, lower-level packages. As such;

  • (2023-12-18) Plans for brainrender, by Alessandro Felder

    Recent maintenance work means brainrender now works with more recent versions of Python and more recent versions of key dependencies (such as vedo). It should also be straightforward to install on all operating systems. We take this opportunity to set out the next steps for this tool.

  • (2023-11-01) cellfinder has moved: version 1 of brainglobe-workflows released, by Will Graham

    Continuing the restructuring of BrainGlobe, the cellfinder command-line tool has moved to a new home, brainglobe-workflows. Please note that we will no longer be providing Docker images for cellfinder’s command-line functionality either - if you were previously using the Docker image, please see the advice in the full changelog.

  • (2023-11-01) Version 1 of brainreg and brainglobe-segmentation released, by Will Graham

    The restructuring of BrainGlobe is underway, beginning with the release of version 1 of brainreg and brainglobe-segmentation (previously known as brainreg-segment). Previously, there were three tools with the prefix brainreg (“brain registration”) that were split across three packages:

  • (2023-10-30) BrainGlobe is being restructured, version 1 is on it’s way!, by Will Graham

    BrainGlobe provides and maintains a number of open-source tools, each of which are provided as Python-based software packages. A number of these tools also come with a graphical user-interface provided by a napari plugin that can be installed on top of the Python package. Whilst there is an advantage to the modularity provided by maintaining separate tools, the same modularity can present challenges and unnecessary difficulties when running an analysis that relies on multiple BrainGlobe tools. Particular pinch points include:
