8 years ago - Be careful about your claims on the benefits of smoothing: I would disagree with them, but I think it's mostly a phrasing issue
- Include images that display the results of your preprocessing steps. For example, you could show smoothed vs. the original slices and images from the PCA
- In section 3.2.1: I'm a little unclear, did you combine all of the runs
across ALL the patients, or just all of the runs for a single patient for
the logistic regression? Make sure to make your language more precise for the
final draft
- Also, you say it is difficult to discern the whether neural activity is due to negative loss response or positive gain respones, but from your regression model, it appears you have two different regressors for these 2 cases - shouldn't you be able to determine something about this by looking at the results for the two regressors? Also, couldn't you try different regressors that perhaps deal with differences and ratios of gain and loss to see if they are more enlightening?
- You very much need to push harder to fill out the results section: at this point there is no analysis of either the regression or MVPA approaches.
