NYU Center for Brain Imaging Events

In this workshop we will present two complementary analyses that aim to go beyond standard fMRI analyses, to establish causal relationships in regional interactions (DCM) or relationships between experimental manipulations, brain responses, and measured behavior within or across individuals (mediation analysis). We will first discuss the theoretical background, including the notion of 'causal' in each approach. After a break, we will follow this with practical demonstration of both methods. This workshop is aimed to be accessible for complete novices but will also be of interest for people who have used DCM or mediation analysis before. We will end with a discussion on the respective merits of each of these tools, and the experimental questions they allow us to answer.
