Spectral Clustering of Brain Regions

Brain regions, classified:

Goal:

In this notebook we implement an open source version of a 2012 PLoS One paper [1].
In this paper it was found, by using the connectivities between 90 regions in the brain of 14 healthy patients, that:

1. It is possible to classify brain regions based on ther connectivity strength between them;
2. The classified regions are roughly equivalent to well-defined anatomical parts of the brain;

Libraries

We make use of sklearn Spectral Clustering for clustering as well as of nilearn plot connectome for plotting the brain regions.

Jupyter Notebook Rendering

Sometimes github won't render the .ipynb so check out this viewer for a rendered version of the notebook.
