  • 1640 Neurons Imaged: MiniXL Microscope Reveals Brain Regions

    1640 Neurons Imaged: MiniXL Microscope Reveals Brain Regions

    Key Takeaways

    1. The MiniXL microscope weighs only 3.5 g and can image 1,640 neurons across a 3.5-mm-diameter field of view, significantly improving the observation of brain activity in mice.
    2. MiniXL can track a substantial percentage of place cells in the hippocampus and image multiple brain regions during social behavior, enhancing understanding of complex actions.
    3. It combines the benefits of previous models, offering a lighter weight while imaging more neurons simultaneously compared to earlier versions like MiniLFOV and Miniscope V4.
    4. The open-source design of MiniXL allows for free access to design files and documentation, promoting collaboration and progress in neuroscience research.
    5. While MiniXL advances laboratory studies, its application in human medicine is still a future goal.

    For a long time, researchers examining the neural foundation of behavior in mice encountered a challenging dilemma. The available small microscopes either had a limited field of view, preventing them from observing more than a tiny area of brain tissue, or were too heavy, causing the mice to not behave naturally. This posed a significant hurdle in understanding how various brain regions work together to create complex actions such as social interactions or forming memories.

    Breakthrough with MiniXL

    Now, the Miniscope extra Large FOV (MiniXL), which weighs 3.5 g and is mounted on the head, is advancing the field of neuroscience by successfully imaging 1,640 neurons across a 3.5-mm-diameter field of view (FOV)—which is 9 times larger than the previous model’s 1 mm². It was able to track 44-53% of place cells in the hippocampal CA1 region on a 2 m linear path, while also imaging the left and right medial prefrontal cortex (mPFC) and the mPFC with nucleus accumbens (NAc) during social behavior in mice. This was achieved using a 5-megapixel CMOS sensor and a single 0.3 mm coaxial cable for streaming data. This milestone was shared on June 11, 2025.

    Comparing the Models

    The earlier models, Miniscope V4 and MiniLFOV, either weighed too much or lacked sufficient power. While MiniLFOV could image around 2,000 neurons simultaneously, it weighed 13.9 g. On the other hand, the Miniscope V4 was lighter at 2.6 g but only managed to image about 200 neurons at once. One might say that the Miniscope extra Large FOV (MiniXL) serves as the Immanuel Kant of the Miniscope realm, effectively merging the advantages and disadvantages of earlier versions.

    Innovation in Imaging

    Its ability to image dual regions, as shown by the simultaneous imaging of the mPFC and NAc, fills an essential gap in tools needed to investigate the neural basis of behaviors influenced by several brain regions, according to the UCLA research team.

    In addition to its technical features, the open-source design of the MiniXL is another noteworthy point. As part of the UCLA Miniscope initiative, all design files and documentation are being freely shared online to reduce technical and financial obstacles, thus promoting faster progress in neuroscience research worldwide.

    Future Applications

    Although this innovation marks a significant advancement for laboratory studies, its use in human medicine remains a far-off goal.
