NEUROMUSCULAR MODEL NOTEBOOK

The neuromuscular model notebook is an interactive tool for studying the underlying mechanisms of muscle force and electromyogram (EMG) generation. The model, which was based on previous studies (see references below), can be used for research purposes as well as a teaching/learning platform.

The notebook was created by Ricardo G. Molinari under the supervision of Dr. Leonardo A. Elias at the Neural Engineering Research Laboratory, University of Campinas (Brazil).

Open this notebook with myBinder Binder or sign in to your Google account to open it on Google Colab Open In Colab

To run the notebook on your local machine, please follow the installation instructions provided below.

Installation Instructions

Dependencies

  • Anaconda (a Python Data Science Plataform)
    • If you already have an Anaconda distribution installed in your computer, it is important to update it:

      conda update conda

Creating the Environment

After installing Anaconda, you have to create a Python 3.7 environment with the following packages: NumPy, Matplotlib, SciPy, Pandas, Ipywidgets, and Plotly. Use the following command in Anaconda terminal:

conda create -n nemu_env python=3.7.0 numpy=1.17.0 matplotlib=3.1.1 scipy=1.1.0 pandas=0.23.4 ipywidgets=7.4.1

Activating the environment

  • Windows users: activate nemu_env
  • Linux/MacOS users: source activate nemu_env

Running the neuromuscular model notebook

  • Use the command jupyter notebook to start the Jupyter notebook application.
  • In Jupyter notebook, open the file 'neuromuscular_note.ipynb'.
  • It is highly recommended to execute each cell in the order of appearance, since there are dependencies between the cells.
