CONN introduction

CONN is a Matlab-based cross-platform imaging software for the computation, display, and analysis of functional connectivity in fMRI data in the resting state and during task. The CONN is known as a SPM toolbox, a suite of commands that is designed to be used as an add-on to SPM. you can find more details in here. You can doload the The CONN from here. Click on the download button to begin downloading the latest version.

This module will focus on the functional connectivity with the SPM-depend tool name CONN. In general, the correlation in BOLD signal between two distinct regions of the brain. This correlation can be analyzed when the subject is doing a task (i.e., task-based connectivity), or when the subject is at rest - relaxed and alert, but not doing any particular task (i.e., resting-state connectivity).

In the following tutorials, you will learn how to perform resting-state connectivity analyses on a dataset. We will use the CONN toolbox to run the analyses, which includes both creating correlation maps for each voxel of the brain, and generating connectomes that visualize the strength of the connectivity between different regions.

CONN with SPM

Before going on, you may want to work through the SPM if you are not familier with SPM. You can check the previous main course SPM, it will introduce you to Matlab and SPM, which you will need to run the CONN toolbox. Note that SPM is a prerequisite for the CONN toolbox, meaning that you will need to download and install SPM before you can use CONN. And the rest of content in the SPM module aren’t required, although a better understanding of how SPM preprocesses fMRI data will prepare you to use the CONN toolbox.

After you have successful install Matlab, SPM and CONN toolbox, now we can play it with a new dataset.
