Overview

Since anatomic MRI is presently not able to directly discern neuronal loss in Parkinson’s Disease (PD), studying the associated functional connectivity (FC) changes seems a promising approach toward developing non-invasive and non-radioactive neuroimaging markers for this disease. While several groups have reported such FC changes in PD, there are also significant discrepancies between studies. Investigating the reproducibility of PD-related FC changes on independent datasets is therefore of crucial importance.

The data are comprised of 27 PD patients and 16 age-matched normal controls in the Neurocon dataset, and 20 PD patients and 20 age-matched controls in the Tao Wu dataset. Both sets contain T1 and resting-state scans.

Experimental Protocol

For the resting-state scan, subjects were instructed to close their eyes and think of nothing in particular without falling asleep.

Data Release Download

Data for the Parkinson's dataset are available for download in an Amazon Web Services S3 bucket.

Each file in the S3 bucket can only be accessed using HTTP (i.e., no ftp or scp ). You can obtain a URL for each desired file and then download it using an HTTP client such as a web browser, wget, or curl. Each file can only be accessed using its literal name - wildcards (i.e. "*") will not work.

There are file transfer programs that can handle S3 natively and will allow you to navigate through the data using a file browser. Cyberduck is one such program that works with Windows and Mac OS X. Cyberduck also has a command line version that works with Windows, Mac OS X, and Linux. Instructions for using the Cyberduck program are as follows:
