Python program to assess motor sequence learning

This is a test game, built to run inside a scanner or while measuring brain activity, in which the subject has to press five keys in a specific order to complete a sequence. The program collects movement time for each execution and finger force data in real time.

Generating anatomical masks using Freesurfer^© (brain imaging)

I needed to find a way to create binary masks from a few Brodmann's areas (e.g. SMA, PMA) and map them on brain imaging data. That way, only selected regions of interest (ROI) are considered in subsequent processing; I get rid of irrelevant (in my experimental paradigm) voxels. To do so, I'm running Freesurfer from the command line on Debian.

Here are the steps (comments in italic, parts to replace between "", code in bold):

• First we process the data and create the labels.

• It will create a matrix to make the mask match the template, the template can either be mri/rawavg.mgz or functionnal space file.

• This will generate the mask, in this instance; it covers the left hemisphere of anterior primary motor cortex.

See below the plot (in yellow) of the mask covering left anterior primary motor cortex (first picture) or left premotor cortex and SMA (second picture) in the anatomical space.

Cloe's Island (2011) : I coded and designed that game for training and entertainement only. Languages used; mainly Ruby.
Pitch: A girl, stranded on an island, tries to survive. Kill those crabs and solve puzzles to progress.
