Mini2P - the brain explorer!

Mini2P is an open-source miniature 2-photon microscope brain explorer for fast high-resolution calcium imaging in freely-moving mice.


Say hello to Mini2P

Application open: 1st Mini2P international workshop

Join the Mini2P workshop in December 2022: Learn to build and use the opensource Mini2P by spending three December days in lovely Trondheim with Weijian Zong and the team at Kavli Institute for Systems Neuroscience, NTNU. The workshop will cover all aspects of Mini2P development, assembly, image acquisition, baseplating and use of the miniscope in freely-moving mice.

Learn more and apply for the workshop!

Say hello to Mini2P

 


In brief

In brief

Development of a miniature 2-photon miniscope for large-scale calcium imaging in freely moving mice allows stable simultaneous recording of more than a thousand cells across multiple planes of densely active cortical regions in a wide spectrum of behavioral tasks without impediment of the animal's behavior.

Highlights

- We made a light-weight 2-photon miniscope for calcium imaging in freely moving mice

- Stable high-quality imaging was observed during a wide spectrum of behaviours

- Activity can be monitored in volumes of over 1,000 visual or entorhinal-cortex cells

- A custom-designed z-scanning module allows fast imaging across multiple planes

Mini2P is open source and available on GitHub

Mini2P is a complete open-source project, we encourage people to use, test, modify and further develop this toolbox.

Mini2P_toolbox on GitHub includes the codes, softwares, 3D models, protocols, and etc. for building and using Mini2P to do freely-moving recording.
