Functional Connectivity and the CONN Toolbox


This module will introduce you to functional connectivity, 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 sample 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.


The CONN toolbox is one of the most widely used resting-state analysis packages available.
