About the brain movie

About the brain movie

This movie is based on data from subject S02 from publication [1] and [2]. This subject happens to have 9 brain sources (isolated using independent component analysis) that corresponded to the sources found in all the subjects (most other subjects only had a partial number of sources). I designed a previous version of the movie which was published in PLOS in 2004 [2] but it was the average of 16 subjects instead of a single subject (the original brain movie is available in the annex of the paper and is also shown below).

For the movie shown on the home page, I used Partial Directed Coherence using an extension of the EEGLAB software called SIFT which was developed by Tim Mullen [3]. This is a brain movie generated using the brainmovie3d_causal function of SIFT which built on the original function I wrote in 2002 [4].

In the original 2002 article, standard phase coherence was used instead of partial directed coherence. An early brain movie from 2002 is shown below.

Also, as a side note, in our laboratory, my collaborator Tim Mullen who co-developed the most recent brainmovie has been involved with Adam Gazelley at UCSF to produced a visually stunning version of the brain movie (I was not involved in this). Although not necessarily more anatomically or scientifically correct, it is so beautiful I had to include it here.
