WebWhen applied to fMRI data, the Gamma Distribution is called a basis function. We call it a basis function because it is the fundamental element, or basis, of the model we will create and fit to the time series of the data. WebThe easiest one to use is a “raw” fMRI image from the same scan, because this has the same resolution and orientation as our statistical map. There are ways to use a higher-quality anatomical scan, but we won’t add that compelxity to our code here. —PSYO/NESC 3505 Assignment 5 cell 55 Reload the image
