Document Summary

Decoding brain activity that uses pattern analysis and classification to get a more fine- brained understanding of brain activity (more detail) as well as a more individualized one (rather than just averaging across participants) Recognize a different picture of a person and be able to discern whether it is the same or not, and make the correct conclusion that this is not the person. Taking a chunk of voxels, put it through a pattern classifier, to determine if a brain is in a particular cognitive state. Using vtc because it is the area associated with object recognition. First (training): present each type of image multiple times and record the average response in each voxel. Looking at the pattern of activity that is associated with a face, averaged out. Looking also at the pattern of activity that is associated with a cat, averaged out.
