Compute single patient Z-Scores from atlas anatomical zone
I have one brain image from a single patient. I have a set of normal pateints. Both, single patient and normal patients are normalised to an SPM template and the NMI space. I also have a brain atlas (...
SPM5 - contrast vectors too long when applied to a new SPM.mat file
Background: I am using fMRI individual level analysis data from my supervisor's previous paper. Before I can perform PPI on the data, I need to update the 1st level analysis batch files since they ...
Is there an equivalence table between the Desikan-Killiany atlas to brodmann areas?
FreeSurfer makes inferences about volume, through the calculation of the surface of the brain. The parametric method (used in SPM) is a voxel-based statistics. FreeSurfer analysis does not map the ...
Choice of reference/mid-slice during SPM slice-timing-correction
I'm trying to figure out the simultaneous-multi-slice (SMS) factor for my MR acquisition, to use during slice-timing correction, in SPM12. The DICOM header obtained during conversion (with the ...
Reproducible Dynamic Causal Modeling/ model based effective connectivity analysis for fMRI
I am doing a Masters degree in Cognitive Neuroscience and was thinking on doing my master thesis on effective connectivity in Theory of Mind. I like the model-based approach of Dynamic Causal Modeling ...
fMRI ROI analysis: independence
In a 2x2 factorial, is it appropriate to look at an interaction at the second-level, group analysis (e.g., using SPM) and define this as an ROI to restrict follow-up main effect contrasts? Or is this ...
