Descripción:
The lectures will discuss how whereas studying patterns of co-variation in brain data is essential to understanding functional circuits, significant challenges exist in attempting to do so with functional MRI data.
Lectures will cover the central ideas of functional connectivity with fMRI. They will start from basic principles and progress to intermediate and advanced topics. Inherent difficulties in modeling functional connectivity (including collinearity) will be discussed in detail. While no “simple” solutions exist, the lectures will provide guidance as to assessing the robustness of the results and ways to improve detecting differences in functional connectivity linked to different task conditions or brain states.
People attending the course are encouraged to read the following papers in advance to help them follow the contents:
