François G Meyer, Department of Electrical and Computer Engineering, University of Colorado Boulder We can read your mind: the decoding of fMRI datasets Very recently, functional Magnetic Resonance Imaging (fMRI) has been used to infer subjective experience and brain states of subjects immersed in natural environments. These environments are rich with uncontrolled stimuli and resemble real life experiences. Conventional methods of analysis of neuroimaging data fail to unravel the complex activity that natural environments elicit. We describe a new method that yields a low dimensional embedding of the fMRI data. The embedding provides a representation of the cognitive activity. We learn a set of time series that are implicit functions of cognitive activity, and we predict the values of these times series in the future from the knowledge of the fMRI data only. We present experiments conducted with the datasets of the 2007 Pittsburgh Brain Activity Interpretation Competition. Reports on this project can be found at: http://ece.colorado.edu/~fmeyer |
