  Quick Announcement: We have multiple Postdoc/Engineering/Researcher positions open within the Miniscope project! Looking for exceptional, creative people interested in instrumentation/tool/software development and who can effectively communicate in both the fields of engineering and neuroscience. A job listing for one of the open positions can be found here. If interested please contact Daniel Aharoni,

Welcome to Wiki! Follow the project on Twitter: @MiniscopeTeam.

We are happy to announce the release of our next generation, open-source Miniscope platform, Miniscope V4. This new system is a substantial leap forward over previous designs and will serve as the base Miniscope platform for years to come. An overview of new features can be found below:

  • >1mm diameter field of view
  • ~1mm working distance
  • +/-200um electronic focal adjustment
  • All achromatic optics
  • 2.6 grams
  • 22mm tall
  • Absolute head orientation sensor
  • Requires ~1/5th the excitation power of previous systems
  • No more soldering!
  • Still uses only a single coaxial cable (down to 0.3mm in diameter) for power, communication, and data.
  • New DAQ software

This wiki site provides a centralized location for sharing design files, source code, and other relevant information so that a community of users can share ideas and developments related to this important imaging technique. Our goal is to help disseminate this technology to the larger neuroscience community and build a foundation of users that will continue advancing this technology and contribute back to the project. While the Miniscope system described here is not an off-the-shelf commercial solution, we have focused on making it as easy as possible for the average neuroscience lab to build and modify, requiring no soldering and simple hands-on assembly. The Miniscope project and are on going projects and will be routinely updated over the coming months and years.

Current Status of Project

The Miniscope project is now in its 6th year of development at UCLA and in its third major revision. Miniscope developers have used Miniscopes to understand how the brain links memories across time in Nature, 2016 and how spatial coding breaks down in epilepsy in Nature Neuroscience, 2019. The work and files available on this site are the most up-to-date public version of our system and will be updated frequently with improvements and new system features. We encourage Miniscope users to contribute to this development process! This wiki is designed for this very purpose.

Initial access to the wiki was enabled mid January, 2016.

Important: Using this system we have successfully imaged Hippocampal CA1, Subiculum, Dorsal Striatum, Parietal Cortex, Prefrontal Cortex, and Visual Cortex using 0.5mm, 1mm, 1.8mm, and 2mm diameter GRIN lenses from either Grintech or GoFoton. (More information on GRIN lenses can be found here).

Guides and Tutorials

A key feature of this effort is to design miniscope systems that are easy to build and use. The guides below will walk you through component procurement, scope assembly, and software installation.

Workshop Resource

We will be holding a pre-SfN workshop November 9th, 2017. For more information visit our MCCS/ICLM Workshop Page.

The Golshani, Silva, and Khakh labs will be hosting free, two-day long Miniscope workshops here at UCLA. We are currently planning at least 3 workshops for 2018. Please enter your information here to request a spot in upcoming workshops.

If you cannot attend one of our workshops, presentations, data files, and workshop videos can be found on our Online Workshop page.
