Hi All,
I have run first with a 3-stage affine registration specifically to look at the hippocampus in a repeated measures design. Volumetric analysis suggests an increase in hippocampal volume between sessions. Shape analysis and VBM, however, are both ns.
How should I interpret this change; would you view this as simply a global increase in GM density? I would have expected the VBM to have agreed, but ROI analysis with TFCE is ns.
Any advice would be very kind.
Thanks.
Sam.
