Welcome to Miniscope.org Wiki! 
 
  
−
The miniature fluorescence microscope described here is based on a design pioneered by Mark Schnitzer's Lab at Stanford  and published in a [http://www.nature.com/nmeth/journal/v8/n10/full/nmeth.1694.html paper in Nature Methods in 2011]. It uses wide-field fluorescence imaging to record neural activity in awake, freely moving mice. The microscope introduced here (miniscope) has a mass of around 3 grams and uses only a single, flexible coaxial cable (0.3mm to 1.5mm diameter) to carry power, control signals, and imaging data. The goal of this wiki site is to provide 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 technology. The initial goal is to help disseminate this technology to the larger neuroscience community so that we can build a community of users that will continue to develop this technology and share on these developments. 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 a standard neuroscience lab to build and modify, requiring minimal soldering and hands on assembly. For more information please visit the [[Overview of System Components|Project Overview]] page. The Miniscope project and miniscope.org are still works in progress and will be routinely updated over the coming months and years. We hope you will contribute to this important process!

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

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 Miniscope.org are on going projects and will be routinely updated over the coming months and years.

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  [http://www.nature.com/nature/journal/v534/n7605/full/nature17955.html how the brain links memories across time in Nature, 2016] and how [https://www.nature.com/articles/s41593-019-0559-0 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.

'''Important:''' Using this system we have successfully imaged Hippocampal CA1, Subiculum, and Visual Cortex using 1.8mm and 2mm diameter GRIN lenses from Grintech. While thinner GRIN lenses should theoretically be compatible with our system we have limited our initial development to larger lenses due to supply and experimental constraints. We are now actively testing thinner lenses as well as pursuing multiple avenues of GRIN lens production (More information on GRIN lenses can be found [[GRIN Lens Information|here]]).

Welcome to Miniscope.org 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 Miniscope.org 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 miniscope.org 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).
