Overview

percept_processing

This code processes JSON files for streamed neural data using Medtronic's Percept PC neurostimulator with BrainSense Technology for time-series and spectral analyses.

Getting started

This code uses the current version of Python on Google Colab. When written, this version was Python 3.6.9.

Data

Neural electrophysiological data are derived from the BrainSense Percept PC neurostimulator (Medtronic). You can request anonymized Percept data from me.

Analysis

For the time-series plots, voltage data from the neural sensing channel(s) and stimulation amplitude data from the stimulating contact(s) are visualized.
For the power spectral density analysis, time-domain data is converted into the frequency domain by computing the power spectral density with a hann windowing function, and spanning frequencies with a bin width of 1Hz until the Nyquist frequency is reached.
