Decoding the Representation of Cognition:the Principles and Applications of MVPA
|
Abstract:
Multi-voxel pattern analysis(MVPA),which is based on machine learning theories,has gained great popularity over the past years as a new approach for fMRI data analysis.By training a classifier,MVPA categorizes multi-voxel patterns tuned by different cognitive states.Compared to conventional voxel-wise methods,this new approach provide higher sensitivity for detecting cognitive representations in the brain.It opens up the possibility for reading out mental states of human beings from the non-invasive recordi...
