"… Recently, a lot of interest has been devoted to desynchronizing delayed feedback deep brain stimulation (DBS). ... This study explores the action of delayed feedback stimulation on partially synchronized oscillatory dynamics, similar to what one observes experimentally in parkinsonian patients. …" Implemented by Andrey Dovzhenok, to whom questions should be addressed.

Usage:

1. Unzip Dovzhenoketal2013.zip into an empty directory.

2. Open the folder in Matlab.

3a. Run PCAgenerator1el.m to compute principal components for the
arrangement with a single electrode. The ode file with a single
electrode arrangement is used.
3b Run PCAgenerator.m to compute principal components for the
arrangements with two or three electrodes. Included ode-files
correspond to the various electrode arrangements considered in the
paper.  Specify the name of the ode-file corresponding to the desired
electrode arrangements on line 9 in odeFileName variable.

4a. Run Sign_subset_1el.m with the outcome of the step 3a to generate
figures 6A and 6B.
4b. Run Sign_subset.m with the outcome of the step 3b to generate
figure 5 and the rest of figure 6.

5a. Run Max_plane_1el.m with the outcomes of the step 3a to generate
figures 8A and 8B.
5b. Run Max_plane.m with the outcomes of the step 3b to generate
figure 7 and the rest of figure 8.
