Neuropixels Probes is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Neuropixels are thin silicon probes that record electrical signals from hundreds or thousands of neurons at once. Developed through a collaboration between the Allen Institute and imec, these probes have revolutionized large-scale neural recording[1].
Neuropixels probes represent a breakthrough in electrophysiology, enabling researchers to record from many more neurons simultaneously than traditional methods. Each probe contains hundreds of recording sites along a slender shank that can be inserted into the brain with minimal damage[1].
Each probe provides 384 or 960 recording channels (depending on the version), allowing simultaneous recording from hundreds of neurons.
The probes are approximately 10 cm long with a shank width of only 70 μm, causing minimal tissue damage during insertion.
Recording electronics are integrated directly onto the probe, reducing noise and power consumption.
Probes can record from multiple brain regions simultaneously and are suitable for both acute and chronic recording configurations.
The original version with 384 channels and a single shank design.
The latest version with 384 channels per shank and options for dual-shank configurations, enabling recording from over 1,500 neurons simultaneously.
Neuropixels data is publicly available through the Allen Institute and can be accessed via the Allen SDK. The Institute has used these probes extensively in the MindScope Program and Brain Observatory.
Neuropixels probes feature densely packed recording sites spaced 15-20 μm apart along the shank. Each site is electrically isolated to minimize cross-talk between channels. The recording sites use titanium nitride (TiN) electrodes for optimal impedance characteristics.
The probes connect to a data acquisition system via a miniaturized headstage. The system supports:
Probes are implanted using standard stereotactic coordinates. The small form factor allows for multiple simultaneous implants in the same animal, enabling recordings from distinct brain regions.
Neuropixels probes are compatible with:
