...Introduction
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](/entities/neurons) at once. Developed through a collaboration between the Allen Institute and imec, these probes have revolutionized large-scale neural recording^[1]^. [@data]
Overview
Mermaid diagram (expand to render)
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]^. [@quality]
Key Features
High Channel Count
Each probe provides 384 or 960 recording channels (depending on the version), allowing simultaneous recording from hundreds of neurons. [@standardization]
The probes are approximately 10 cm long with a shank width of only 70 μm, causing minimal tissue damage during insertion.
Integrated Electronics
Recording electronics are integrated directly onto the probe, reducing noise and power consumption.
Versatile Recording
Probes can record from multiple brain regions simultaneously and are suitable for both acute and chronic recording configurations.
Versions
Neuropixels 1.0
The original version with 384 channels and a single shank design.
Neuropixels 2.0
The latest version with 384 channels per shank and options for dual-shank configurations, enabling recording from over 1,500 neurons simultaneously.
Use Cases
- Large-scale neural population recordings
- Mapping functional connectivity across brain regions
- Studying neural dynamics during behavior
- Chronic recordings in disease models
Data Access
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](/projects/mindscope) and [Brain Observatory](/projects/brain-observatory).
Technical Specifications
Recording Sites
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.
Data Acquisition
The probes connect to a data acquisition system via a miniaturized headstage. The system supports:
- Sampling rates up to 30 kHz per channel
- Configurable gain and filter settings
- Digital output for noise-free signal transmission
Surgical Implantation
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.
Compatibility
Neuropixels probes are compatible with:
- Open Ephys acquisition systems
- Intan Technologies headstages
- Custom FPGA-based recording systems
