Sep 11, 2013 — Functional Brain Network Visualization — Now that we have (finally) come up with a correlation matrix to describe the relationship of voxels across the brain, let’s explore some simple methods from graph theory.  To make this analysis somewhat more simple, I’ve thresholded my brain network...

Sep 9, 2013 — Tracing a Functional Brain Network — I’m reading about different ways to understand and process functional data, and so methods from graph theory serve as good candidates.  I’m excited about these methods simply because I’ve never tried them out before. Creating the Graph Assess Correlations between... Read more

Aug 31, 2013 — Exploring Raw Functional MRI — I’m curious if using a mean timecourse to represent a region is a good idea or not.  What I did is, for a functional timeseries with 140 timepoints, I wrote a script to mask the data for a region of... Read more

Aug 31, 2013 — Exploring Raw Structural MRI — I’m happy to report that I’ve passed my Qualifying exam, and so the past week has largely been filled with what I consider “fun” work, e.g., playing with data with no pre-defined goal or purpose, and reading about methods just... Read more
