Founding developer Daniel Aharoni

After the sweeping success of the V3.2 Miniscope Daniel Aharoni continues to raise miniscope technology to new levels from his UCLA lab focussed on developing neuro-behavioral recording techniques for freely behaving animals. Significant contributors to the V4 were also the Cai and Shuman labs at Mount Sinai, and the Blair lab at UCLA.

It builds on the GolshaniSilva, and Khakh UCLA labs' initiative coordinated by Daniel Aharoni of making Mark Schnitzer's pioneering invention (Nature Methods 2011) open source. 

The UCLA miniscope community maintains a WiKi to help disseminate this open source technology to the larger neuroscience community.


The V4 is a leap forward in miniscope technology. It will serve as the platform for a new generation of miniscopes for years to come. This high-end solution will help to advance and disseminate miniature microscopy to the fast increasing open-source neuroscience community.

Miniscope V4 uses wide-field fluorescence imaging to record neural activity in awake, freely moving mice. V4 miniscopes from LabMaker come fully-assembled, tested, and ready to use. It is compatible with the Data Acquisition System (DAQ) with V4 firmware.

KEY FEATURES

  • >1mm diameter field of view
  • ~1mm working distance
  • with electronic focal adjustment of +/-200um with electrowetting lens; no more mechanical sliding in order to focus
  • all high resolution achromatic optics (no internal GRIN lens)
  • 2.6 grams, 22 mm tall
  • absolute head orientation sensor
  • requires ~1/5th the excitation power of previous systems
  • still uses only a single coaxial cable (down to 0.3mm in diameter) for power, communication, and data. 

CONTENTS 

  • Fully-assembled and tested Miniscope V4
  • Lens configuration 1
  • aluminium objective sleeve for easy, repeated mounting (for base plate variant 2)
  • one separate base plate variant 2 with screw and screwdriver
  • 300 cm coaxial cable, 1 mm diameter, Hirose U.FL connector

FULFILLMENT

Orders received for the first batch will be fulfilled in September 2020. 

Next batch fulfillment will be done in mid-October 2020.

USING A MINISCOPE

is straightforward when you follow the detailed UCLA step-by-step instructions. (requires prior registration with miniscope.org)
