**laura**: Local Auto-Regressive Average

laura: Local Auto-Regressive Average

This repository contains the source code for the Local AUto-Regressive Average (LAURA) inverse solution as described by de Peralta Menendez et al. (2001, 2004). The code is based on mne-python, a powerful EEG library for python.

Personally, I think this linear inverse solution finds the neural sources underlying M/EEG measurements with great success and is a valuable option among other inverse solutions such as minimum norm estimates and (e)LORETA.

Dependencies

• mne
• scipy
• numpy

That's it!

Installation from PyPi

Use pip to install laura and all its dependencies from PyPi:

pip install laura

Quick Start

The following code demonstrates how to use this package:

from laura import compute_laura

stc = compute_laura(evoked, forward)
stc.plot()

, where evoked is an instance of mne.Evoked and forward is an instance of mne.Forward. For further explanation on mne and its objects please refer to the mne website.

I would be happy if you would cite this package, too:

LAURA was calculated using the laura python package available at https://github.com/LukeTheHecker/laura.

Limitations

The current implementation is limited to:

• fixed dipole orientations
• time-domain EEG data
