Neuropixels
2.0 Quad Base
The Neuropixels 2.0 QB neural probe is the most advanced CMOS digital integrated microsystems platform.
The Neuropixels 2.0 QB multishank neural probe is the most advanced CMOS digital integrated microsystems platform. With four times the number of channels (n=1536) of the standard Neuropixels 2.0 probe, the spatial coverage of the recorded area can be quadrupled, allowing single unit recording at an unprecedented scale. The probe features 5120 low-impedance TiN recording sites densely tiled along four thin, 10 mm-long, straight shanks. The 1536 parallel low-noise recording channels integrated in the base enable simultaneous full band recording of hundreds of neurons.
On-chip circuitry for signal conditioning and digitization results in a small and light-weightpackage allowing the implantation and simultaneous use of multiple probes in close proximity.
​​
Neuropixels probes enable long-term monitoring and dense sampling of single cell activity as well as larger neuron populations in awake and anaesthetized animals.
​​
The probes connect to the custom-made recording system via a miniature and light-weight headstage (HS_2020), which is an essential interface board for reliable power supply, probe configuration, data streaming and system/probe diagnostics. Each headstage can connect two probes simultaneously.
​​
A dedicated cable (CBL_2020) streams the data to a PXIe based Card and Control System or OneBox, and the probes are supported by the SpikeGLX and Open Ephys software.​

This probe features four shanks with 5120 recording electrodes in total (1280 electrodes per shank in two dense linear rows ), and 1536 read out channels.
Fully packaged probes can be purchased with either of two cap versions glued to the probe base: a flat silicon cap or a metal cap with dovetail mounting structures.​
​
​Either cap type serves as a light shield for the base electronics and allows accurate and well-aligned attachment of custom holders.
​
The metal-capped and silicon-capped probes are identical in every way except the cap.
​
The metal-capped probe is compatible with the Neuropixels 2.0 probe holder, designed at the HHMI Janelia Research Campus.
