Neuro Digital Signal Processing Toolbox

_ _ _ _ _ _ _

Tools to analyze and simulate neural time series, using digital signal processing.

Overview

neurodsp is a collection of approaches for applying digital signal processing, and related algorithms, to neural time series. It also includes simulation tools for generating plausible simulations of neural time series.

Available modules in NeuroDSP include:

• filt : Filter data with bandpass, highpass, lowpass, or notch filters
• timefrequency : Estimate instantaneous measures of oscillatory activity
• spectral : Compute freqeuncy domain features such as power spectra
• burst : Detect bursting oscillations in neural signals
• rhythm : Find and analyze rhythmic and recurrent patterns in time series
• aperiodic : Analyze aperiodic features of neural time series
• sim : Simulate time series, including periodic and aperiodic signal components
• plts : Plot neural time series and derived measures
• utils : Additional utilities for managing time series data

Documentation

Documentation for the NeuroDSP module is available here.

The documentation includes:

• Tutorials: which describe and work through each module in NeuroDSP
• Examples: demonstrating example applications and workflows
• API List: which lists and describes all the code and functionality available in the module
• Glossary: which defines all the key terms used in the module

If you have a question about using NeuroDSP that doesn't seem to be covered by the documentation, feel free to open an issue and ask!

Dependencies

NeuroDSP is written in Python, and requires Python >= 3.6 to run.

It has the following dependencies:

• numpy
• scipy
• matplotlib

Optional dependencies:

• pytest is needed if you want to run the test suite locally

We recommend using the Anaconda distribution to manage these requirements.
