neurokit2
The Python Toolbox for Neurophysiological Signal Processing.
Decision gist · record as of 2026-08-14
Yes, if you work with physiological signals and want to avoid building signal processing pipelines from scratch. The package is actively maintained, permissively licensed, has low install friction, and is backed by published research. The Pre-Alpha classifier is a minor concern—verify current stability for production use—but the active repository, recent releases, and substantial community adoption suggest it is reliable for research and clinical applications.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.10; eight runtime dependencies (numpy, scipy, scikit-learn, pandas, matplotlib, pywavelets, requests, setuptools) will be installed automatically.
- Low install friction with a pure-Python wheel.
- Maintenance is active with recent commits and a substantial community (2324 stars).

What it is and what it does
NeuroKit2 is a Python toolbox for processing and analyzing physiological signals commonly recorded in research and clinical settings. It wraps complex signal processing operations (filtering, peak detection, feature extraction) into high-level functions that researchers and clinicians can call with minimal code—the description example shows analysis completed in two function calls. The package supports multiple signal types: ECG (electrocardiogram), RSP (respiration), EDA (electrodermal activity), EMG (electromyography), PPG (photoplethysmography), and EOG (electrooculography).
The package is built on established scientific libraries (numpy, scipy, scikit-learn, pandas, matplotlib) and provides both simple "master" functions for standard workflows and lower-level functions for custom pipelines. It includes example datasets and supports signal simulation for testing. The codebase is actively maintained, has a published peer-reviewed paper (2021), and is designed to be accessible to users without deep expertise in signal processing or programming.
Use it for
- Preprocess and extract heart rate variability features from ECG recordings for cardiovascular research.
- Analyze electrodermal activity (skin conductance) peaks and troughs in emotion or stress studies.
- Extract respiratory rate and variability metrics from respiration signals in sleep or exercise studies.
- Simulate synthetic physiological signals to validate custom analysis pipelines before applying them to real data.
- Perform event-related analysis by aligning and processing multiple signal types around experimental events.
- Locate and delineate ECG waveform components (P, Q, R, S, T waves) for detailed cardiac morphology analysis.
