I recently received an email with some relatively basic questions about FMRI, and both the question and answers might apply to some of you. Admittedly, I am not 100% sure about the weighting of the regressors for the ANOVA, but I think it's pretty close. Whatever, man; I'm union.
Some of the words have been changed to protect the identity of the author.
Thanks for your message. My background is in medicine and I am trying to do fmri research!
I will be grateful for your help:
1. How do you interpret the results of the higher and first level fsl analysis - I am used to p values and Confidence intervals - are fMRI results read in a similar way?
2. Importantly- I have a series of subjects and we are interested to look at effect of [a manipulation] on their response to [cat images] over one year, we have four time points one before the operation and three after. These time points are roughly 4 months apart.
Our Idea was to see how the response to [cat images] changes over time- with each subject serving as their own control- How do I analyse that? We have some missing time points as well- subjects did not come for all the time points!
Hi Simon,Congratulations on your foray into FMRI research; I wish you the best of luck, and I hope you find it enjoyable and rewarding!
Hope this helps!
