The engineering behind Neuropixels is led by Tim Harris at Janelia Research Campus and is delivered by the engineers at IMEC, the nanoelectronics research center.

Version 1.0

The first generation of Neuropixels probes (single shank, ~1,000 recording sites) are available at cost price at www.neuropixels.org. To test them during development and guide further refinements, Tim Harris teamed up with scientists at UCL and Allen Institute for Brain Science. The results of the work were published in 2017 (Jun, Steinmetz, Siegle, Denman, Bauza et al, Nature 2017)

The UCL team included Principal Investigators John O'KeefeKenneth Harris, and Matteo Carandini, and postdocs Nicholas Steinmetz, Marius Bauza, and Marius Pachitariu. This work was made possible by a Strategic Award from the Wellcome Trust and by funds from the Gatsby Charitable Foundation, the Allen Institute, and the Howard Hughes Medical Institute.

Version 2.0

Research is underway to develop further versions of the probes: four-shank probes with ~4,000 recording sites (ideal for chronic recordings), and optrodes that combine recording with optical stimulation (for optogenetic experiments). 

To test these probes during development and guide their development, Tim Harris teamed up with scientists at UCL, Allen Institute for Brain ScienceNTNU, NERF, and Champalimaud

The UCL team is led by Matteo Carandini and coordinated by Nicholas Steinmetz. The other Principal Investigators are John O'KeefeKenneth Harris, Michael Hausser, and Adam Kampff. This effort is funded by a Collaborative Award from the Wellcome Trust from 2017 to 2022. 

Preliminary results of this work were released in 2020 (Steinmetz, Aydin, Lebedeva, Okun, Pachitariu, et al, bioRxiv 2020).
