Fmri searchlight analysis
WebSearchlight analysis (information mapping) with pattern classifiers is a popular method of multivariate fMRI analysis often interpreted as localizing informative voxel clusters. Applicability and utility of this method is limited, however, by its dependency on searchlight radius, the assumption that information is present at all spatial scales ... WebDec 23, 2024 · Table 2 is a script demo to understand how to conduct a searchlight-based analysis for fMRI data. We could first calculate the fMRI RDMs within each searchlight blob and then obtain similarities between fMRI RDMs and a behavioral RDM or a coding model RDM, which is constructed based on the hypothesis all over the whole brain. ...
